Hi L D
I’m sorry to hear that you’re having trouble with your Teams notebook. Here are some steps you can try to recover your work:
Open the shared notebook where you lost recent notes.
Choose the View tab and Deleted Notes.
If your deleted notes are found there, right-click the page tab that you want to restore, and then use the Move or Copy command to put the notes back in their original location.
If the above steps don’t work, you might want to try restoring the library:
Go to the gear icon in the upper right. Select Restore this library.
Select a date range, select your files. Click Restore.
I hope this helps! Let me know if you need further assistance.
Kind Regards
