Take this junk off the market
As so many others have mentioned: can’t get it out the tube. I bought the most expensive thinking it was the best. Two tubes and both were dried up in the tube. I put so much pressure on the caulking gun that it bent the plunger on my caulking gun and nothing came out the tube. Wasted time and money, and pushed my project back by a whole day. Please do not reply with your generic, insincere, copy/paste “We are sorry” response. For the sake of your brand name, pull this junk off the market.

Thank you for posting your feedback. Based on your description of the difficulty encountered while attempting to apply the product, it would appear that you may have purchased material that is beyond shelf life and/or the inner foil seal was not properly punctured prior to your application attempt. At your convenience, please contact DAP’s Technical Customer Service Department at 888-327-8477 so that we can obtain some additional information from you. When calling in, please be sure to have the package (cartridge) available, as we will need to verify the production code in order to determine the date of manufacture and so that we can reach out to the store where it was purchased, as DAP does not have direct control of stock rotation/inventory management at the retail store level.

Product turns yellow if you don't paint
I bought the most expensive caulk to not deal with quality issues but this caulk turned yellow on every baseboard that it was used with. I used two dap products and both are trash.
Caulk was never cleaned, wiped and the only thing it was exposed to was dust which is visible, water on smooth rag which was used to smooth the caulk during application and home air.
The GE product is far superior. IF you intend to use this, paint over it.

Thank you for posting your feedback about DAP 3.0 Kitchen, Bath & Plumbing High Performance Sealant. We are sorry to hear about your experience with this product. The most common cause of "yellowing" is exposure to oxidizers (bleach/bleach like cleaners), natural oils/petroleum oils and solvents (as well as their vapors). At your convenience, please contact DAP’s Technical Customer Service Department at 888-327-8477 so that we can obtain some additional information from you and arrange to obtain a sample of your remaining product for evaluation.

I used this because it was recommended in the instructions for the tub surround I bought. Normally I love DAP products (DAP 230 is great). I was expecting this to be a bit challenging to work with, but it wasn't so bad. Just have some mineral spirits handy for any issues. The problem is that, after a few months, the white had definitely yellowed quite a bit.
Now, you'll see where others have complained, and DAP reps say it doesn't unless "it's exposed to some sort of chemical that reacts with it". So here's the thing. I am a very lazy husband. So it took me MONTHS to finish the bathroom. Thus it was not used, certainly not as a bathroom. There were no chemicals. Barely even light. It was like a nearly-perfect science experiment. And it yellowed.
I'll attach a picture where I went to finish filling in the gaps and screw troughs. It's kind of obvious what's new and what's a few months old with no use or wear (hint: the top and bottom of the corner bead). And it's kind of obvious that nobody in their right mind would have used the tub in that shape. And it wasn't plumbed, anyway. All the tubes were bought from the same box.
The stuff was nice and pliable, stuck well, and no signs of lack of power as an adhesive agent. But I wouldn't use it where it's going to be seen. I'll stick to DAP 230 for that. And in fact I went over any visible DAP 3.0 with DAP 230.

This is the first caulk that adheres to my bathtub and surround. I have used many products prior to this one. They would either crack, peel, or just get moldy and fail quickly (Generally within a month) This one has held super well so far, and has been on my tub for two months now with still looking like new, and still sealing tight to both surfaces with no cracks.
Beware however... This is SUPER tacky, super adherent, and super tough. I got this on my hands, and it took quite awhile to all come off. To me, this was actually a good thing. It meant it would hold to my tub. I read others complain about the difficult to remove/clean. That is true. So be careful with it. maybe also tape off the areas so it doesn't spread too much, and do it nicely. I bought the kit to make it look nice. Clean any stray parts up as quickly as possible.

This is the stuff to use to seal a bath or shower surround. I have read many reviews of people applying it incorrectly so I decided to offer some suggestions because there are few other caulks that will work long term on shower surrounds.
First, don't even think about applying DAP 3.0 without painter's tape. You cannot even begin to do it without smearing it all over the place. I highly recommend Frog Tape. The blue stuff is not good enough to caulk with. Trust me. Put down two pieces of tape in a parallel line about 1/8' to 3/32" apart over the seam you want to calk. Lay down a bead of calk over the seam. Wear nitrile gloves and dip your index finger into a cup of 91% rubbing alcohol. Smooth out the calk line wiping your finger off frequently with paper towels. Do not use mineral spirits as the caulk tube label suggests. It will damage the plastic that is used on tub surrounds and it stinks to high heaven. 91% rubbing alcohol is good enough and can also be used to clean up any caulk that gets on the surround where it shouldn't be. The alcohol smell dissipates is less than a minute.
Lift off the tape being careful not to have the caulk laden tape brush up against the surround or you will have a clean-up job. Depending on how the caulk line looks, you could take one more swipe at it with your alcohol coated finger, but after that, stop there or you will start smearing it all over the place. You are better off to leave it alone after you lift the tape.
I wouldn't use the clear version of this caulk since it has many documented complaints of yellowing. I have never had the white version yellow and it looks good for years.
Ignore the silly comments that say things like "This caulk is no good because it comes out like glue" or "I couldn't apply this because it smeared." It's just a matter of doing it right, folks. It's really good stuff.

Per manufacturer's instructions, I used DAP 3.0 White Advanced Kitchen, Bath and Plumbing Sealant to seal our new 5-piece Sturdifit #40194 glue-up tub surround made of 5/32" high-impact polystyrene. I wiped down the area I needed to caulk with 91% rubbing alcohol, then I cut the tip at a 45-degree angle for a 3/16" diameter bead and poked a long, sharp, 3/16" diameter bamboo skewer down inside the tip to puncture the inner sealing membrane. The fresh caulk is the consistency of sour cream, but once the tube has been opened, the caulk in the tip thickens overnight to that of ice-cream and must be expelled and discarded before running new beads. I didn't use any masking tape and always push the caulk gun forward, instead of pulling it to run my beads, being careful to slowly squeeze out just enough caulk so it won't "snowplow" ahead and back over the tip. I let it set up a few minutes before dipping my bare finger into a small medicine dosing cup of 91% rubbing alcohol to smooth the bead, re-dipping every 3" or so. I went through and half a box of tissues, constantly wiping excess caulk off my finger and the tip of the caulking tube because it's sticky and therefore messy to work with, but the results turned out great. Rubbing alcohol works to remove the dried milky caulk/alcohol residue as well as any thin smears of caulk bordering the seams even two days later. I let it dry 24 hours before using the shower and it didn't shrink, soften or dissolve like the horrible DAP Kwik-Seal latex bathroom caulk. After a month, the DAP 3.0 remains stiff, yet flexible and is staying put. I painted the caulked edges of the tub surround with two coats of 100% Acrylic Latex gloss paint to match the walls and it covers & sticks to the caulk just fine. It even worked to "glue" the 1/4" white acrylic water diverters I made in each corner (see photos) before caulking them in the next day.
Bottom Line: Messy to work with, but if you're patient, it yields good results and is paintable. Time will tell how resistant it is to mold, mildew and cleaning chemicals.
