Hello,
My name is Rita and I'd be happy to help you resolve your issue.
May I know if you tried deleting the notes on OneNote page or you went through OneDrive?
If your reply is Yes, kindly try the following option that works for me.
I have tried deleting notes on OneNote page but could not delete multiple notes.
So I went to OneDrive, Clicked on My files. Then I opened Notebooks folder. Selected the notes I wanted to delete and clicked delete.
I recommend you try deleting your notes through OneDrive.
If this option helps, please click Yes to help other users with a similar request.
Best Regards, Rita.
