Hi,
I have recently started having problems with Onenote - just the Windows 10 version. I can't sign in to my work account (which uses SSO) anymore, it sends me to the SSO page, lets me login, then nothing happens - if I go back to settings - accounts, the account is there but it says "needs attention" under it. If I click on the account it sends me back to the SSO page and the whole thing starts again.
I don't have this problem with Onenote 2016, but I've been using the Windows 10 version lately.
I have tried resetting the app in settings and have run the Powershell command to remove it and reisntall from the store, neither of these work.
The SSO page for my work look a bit different this week - I wonder if our IT team has upgraded it and now it is causing problems?
