Hello. I had a new vinyl installed in the bathroom about a month and a half ago. Has been ok but last week bubbles suddenly appeared in the area next to the door threshold (pls see attached photo). There are no bubbles in any other area.
Having googled the issue, some results say bubbles on vinyl is because moist air got under the vinyl, but I'm not sure if it's the same in my case.
Appreciate any feedback and tips on how to treat it.
