Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Changing to TCP in PIA worked for me. OneNote is now syncing.
I turned off the cyber sec setting and changed to tcp from udp, as suggested in a prior post. My office apps were able to autosave on One Drive. Based on this post, I re-enabled the cybersec setting and kept the tcp option. I'm still able to autosave. I'll keep testing, but it's nice to have the cybersec enabled.
