Yea ask first, sometimes they are OK with it. Onenote has this really seemingly useful feature that records as you type. So if you’re taking notes and miss something you can click next to your notes and hear the recording exactly from that spot then add to your notes later. I think this might be useful for someone who takes notes, but since I have never been that person, I’m just guessing here. I always thought it was a handy feature, like lots of other things in OneNote that I never actually used.
