Hi @Arne Østerås Qvenild thanks for reachiing out!
Here’s what you can try right away to recover the content:
Check the board’s version history
Open your board → click the board name in the top-left corner → select “Board history” (if you’re on a paid plan).
You may be able to restore an earlier version before the content disappeared.
Search for your board or items
From your dashboard, use the search bar to check if the content might have been moved or duplicated to another board.
Check your trash
Deleted boards and items can sometimes be restored from the Team Trash (available for Team Admins).
If this does not help, I’ll convert your post into a support ticket so the Miro team can look into your case directly and verify what happened in the backend. Let me know how it goes!
