If you'd like to restore a mind map that was deleted by mistake, follow the steps outlined here.
If there are topics in your mind map that got deleted by mistake, use the keyboard shortcut ⌘Ctrl+Z to undo those changes or use Versions History to view or restore any changes made to your mind map.
If you've checked the trashcan and your mind maps are still missing, make sure you're not logged in with a different email then the one you used when you created the mind maps. It's the most common cause of missing maps!
