"undo" functionality bugs

Undo is still not working correctly. Sometimes when I click “undo” after an action (or hit the ctrl-z hotkey) it does absolutely nothing. Also, often it undoes the wrong action, which is confusing and aggravating. So very often I’ll, say, archive a message and then undo that, but instead of undoing that action, it will undo something previous, like a prior message I had deleted. WTF.

As in the other issue - you have a Pro licence and paid for eMC support.
