Undo, redo buttons not activated

Can’t undo…
I suppose blue buttons are clickable and grey is not.
The undo and redo buttons are grey and not working on keyboards too.


Hello, the undo/redo button should work well. Have you checked that you did this operation after making an edit in the PDF or in the mind map? These features are only activated when you have edits actions.

Best regards,


Kind Regards,
