I have a little problem and i don’t know how to fix it. I have been using Miro for a important school project with my classmate. Today when i opened our board everything was gone. In the overview of all my boards i could see that somebody (no idea who this person is) changed the board but when i open the board and look at the members i am the only one in it, my classmate is not even mentioned there anymore. Does anybody have any idea how to fix this or what even is going on.
