OneNote sign in and synching problem!

The error came back... Same problem as before.

Had this issue everyone is having start yesterday. This morning issue seemed fixed for about 30 minutes but the same issue has returned. Hope this can get fixed ASAP!!!!

To Microsoft support or to whom it may concern:

=================================

The OneNote for Windows 10 is still working on my PCs this morning, but I'm afraid they might start breaking as before. Two users reported that their apps were working briefly this morning and just stopped working. Whatever the OneNote team is doing (testing features or fix on servers, trying out a more ideal fix?), please communicate to the OneNote team that their changes are affecting live OneNote for Windows 10 customers. It is possible that another team in Microsoft is changing functionality in user account services (authentication, ...) and inadvertently affecting OneNote? **** After many users got affected, I'm not sure why there is no update from Microsoft on what happened or what to expect. It's hard to tell whether this is due to work being done for enhanced OneNote future release or some new user account feature for Windows 11, but users need a stable environment to be productive. This wasn't just some server being down or performance issue, and it blocked many users from making edits on OneNote for Windows 11.

The issue never resolved for me. All of my symptoms are described above. :-(
