Snap remove permission denied?

(Sorry if this is a duplicate, I couldn’t see my original post which I posted in category “other”, so I’m trying category “snap” now)

How do I remove a snap no a multi-user system? For some reason snap seems to be connected to the “first” user in alphabetical order, and when performing snap remove firefox for example, I receive a permission denied error pertaining to another user’s snap folder.

How to resolve?
