Using the Teams UI, I entered meeting notes, including hyperlinks (via CTRL-K) to some documents. Those links work both in the Teams UI and the web UI. When I open the notes in OneNote though, the hyperlinks are not there.
I can edit the note in the web, OneNote, and Teams, and all changes get sync'd, but the hyperlinks added in Teams do not get sync'd to OneNote. I have plenty of other hyperlinks in OneNote added from ON directly, so it seems to be a slight glitch in how Teams creates the note.
