Hello,
I use Onenote app most of the time (OneNote 2016, MSO).
But when I create a page in Onenote Web, it then appears in my OneNote Feed and it's impossible to delete it.
In the example you will see, page 3 still exists, but the other 2 pages have even been deleted from OneNote. (Attempt for me to erase the notes in the Feed). It's been months, several times a day I try to erase them, but it comes back.
I tried with the application, I tried on the Web with Chrome, with Edge, with Firefox, on my iphone, on a PC , on a MAC, on Onenote 2013 too. Close, déconnect all the account, reconnect, shutdown, etc.
They always come back.
It only happens if I create them by web or not my phone. I can't update because it's the company account.
I can't delete the app either to reinstall it. Anyway, it's the only one that doesn't cause this problem.
