OneNote Gem Add-Ins

Phenomenon:

Some of the section groups, sections in a notebook suddenly disappear and are not displayed.
But some of the section groups and sections of this notebook are still displayed.
 
After observing for a while, I found that when OneNote was syncing, the display of section groups and sections would change.
They are not fixed, and sometimes they show more section groups and sections; Sometimes they are gone.
 
 

Temporary Solution:

It is estimated that this is a continuation issue from the previous OneNote incident.
Event: 2024.8.27 All Notes and Sections Disappear Except Notebook Names in OneNote. Error: 0xE00009C8 bb0ur

 
This is a problem with the Microsoft server, which is now only present on the Windows Office OneNote client.
Other OneNote clients are not affected.
 
It is estimated that it will take a while for Microsoft to fix this problem, and it can be replaced by OneNote for Windows 10 first.
