How to stop showing sync error while writing

I am teaching remotely by sharing my OneNote screen.  Regularly (every 5-10) min the error "Working offline (an error occurred" pops up on the screen and then within a few seconds to a minute disappears.  I assume that OneNote is disconnecting and then reconnecting to the server, and all the material does get synced so I am not trying to solve a sync error.  I would like to stop the pop-up from showing the error because it consistently appearing and disappearing and jumping my writing space up or down is maddening, especially while in the middle of class and presenting to students.  Is there a way to stop this notification from appearing without disabling sync?
