Problems. We got problems! Here's what it looks like when LVP goes bad, and why it went bad.
This is an installation we had to re-do. Two big problems: 1) Lined up seams of planks. 2) Didn't click together properly.
This was done by an unsupervised crew of volunteers who declared themselves flooring experts. They were not. If they had even read half the instructions, this wouldn't have happened. The pattern issue is egregious. It not only looks bad to have end seams lined up, it also creates a weak floor. The best lock is a semi-random 3-plank offset. Pros are really good and this and make it seem 100% random. Oddly, some people like a 2-plank offset which creates an "H" pattern. It think it is terrible and weakens the lock.

Close up of the failed seams. (And more end seams too close.) I actually think they never were locked to begin with. The rubber tongues are gray and if you have gray floor, you sometimes can't see it. I emphasize with my volunteers that you must wear your glasses and then run your fingernail. 100% of the seam from top to bottom must be tight. Even 10% not locking will cause separation.

Another bad seam in this room. At first glance, looks OK, then you can see the tongue. The gap is about 1/16" which is a disaster. (Look diagonally from left bottom up to top right, and also notice the ends are not aligned.)

Let's talk trim. A good trim job won't have huge gaps at the bottom like the gray LVP in this picture. Also, door casings will be undercut and the LVP slide under in an expert fashion. This takes finesse to do correctly. I should say I won't criticize the previous volunteer crew too much for this high trim. It was a mobile home with a lot of rot. The floor may sag here.
I didn't do the gray, I did the dark. She wanted this color and product. It was a sticky-back LVP which was super cheap and I would not recommend. But since she paid for part of it, I wasn't going to say no. We gave her a good subfloor so maybe it worked.
One more thing: notice the threshold-transition. Another bad install method is to not properly space out the nail holes. You want them nice and even. Also, high end installs use better thresholds. It is one way to get that "exclusivity".
