We have a notebook tab in one of our teams that when you go to it in Teams, you see a banner at the top that says:
If your site isn't loading correcctly, click here.
When you click "here", you get a message saying:
Last time we checked, this site wouldn't load inside our web app.
Here is what we can do:
Go to the website
Reload this tab
If you reload the tab, you still see the banner telling you the site isn't loading correctly. If you go to the website, it opens the notebook in OneNote online. However, if you try to edit the page (I tried to create a new page), an error pops up saying you do not have permission to the section. When I open the notebook in the Windows 10 OneNote app (PC version), it works fine. Has anyone else experienced something like this? Did it resolve itself with time, or were you able to fix it?
