While editing my process map I must have accidentally deleted an entire layer. I've tried to undo but the undo button does nothing. Tried Revision History but it's unclear if it will have previous revisions. I've lost a lot of work here and I'm really not happy that I have to upgrade to compensate for an undo button not working and don't know if it will even work.
Lucid Chart your app is great but this is a real let down!
