We have found that with multiple users in our company, the Meeting Notes Capture app will not send meeting notes to OneNote if there are more than 1 attendee in the meeting. We don't see an error on PowerApps (it seems to think it's sent the data correctly), but in OneNote on desktop we see a continuous "Loading Page" screen, and on OneNote online, we get the following error:
