I can not edit my board. I am an owner and the only user, the board is not marked as "View Only", but when I open it I can't neither created new text or shape, nor edit any existing. There is no error message or any indication. Just when I double-click on, let's say a text, I can see that for a half of a second the text component changes into editable mode and the resets, component even becomes unselected (this is the state when you left-click on a component once).
Re-login did not help. Also, I can edit my another board.... what's going on?
