I am the only admin and user on my account, when I tried to view my own boards, it asked for admin approval, but I couldn't figure that out either.
Then, to my great dismay, when I selected "offline mode" they all disappeared.
I was prompted to log in so I don't lose my account, and delighted when I logged in that my 5 or 6 boards were still there...moments later frustrated and then sad they disappeared. I was initially on chrome browser on Samsung Galaxy S23, then it said things were best on the app, which needed an update. Maybe I should have tried to be on my laptop instead, will log in there later to check if anything still exists
