I just went through that on a small apartment above a garage I'm remodeling. The sub floor was not strong enough, it was amateur built. All the square adhesive tiles were turned up on the edges. I'm almost certain because walking pressure with the soft subfloor made the centers depress and worked the edges up.

It's a weird apartment, the kitchen is on two levels (hilly lot), I took the tiles out of the lower part and the adhesive remaining on the floor was so intense it would pull my shoes off if I walked on it. I tried using cornstarch, hoping the sheet vinyl adhesive would still work, the cornstarch did not work well, then I used citrus paint remover and one of those paint scrapers with a handle and a four sided piece you can turn around on the business end. I scraped up a bunch of junk and then I realized I needed to put three-quarter plywood down. The sub for really needed beefing up. So all that time trying to scrape up the residue had been wasted.

The upper section had a better subfloor, but the residue about as bad as below. The worst part would've been positioning the large sheet vinyl, one piece, I didn't want the bleeping edges turned up again. What I do is positioni the vinyl, get it in the right place and then roll up half of it, put the adhesive down roll it back, and roll the other half and do likewise. Sticky residue would've ruined my piece of vinyl before I got it in place. I would not have been able to move it. So I put down 5/16 ply on the upper. Worked great.
