Are shared users able to turn off motion detection?

I just installed my Ring doorbell about a week ago. I added my SO as a shared user. Since then there have been 3 different occasions that he had returned home when I was not there without me getting a notification. Otherwise, I get notifications for everyone else that comes near the door. Is it possible that he is turning off motion notifications or motion detection temporarily so that I don’t know when he gets home? If so, is there anywhere that I can see if that is what is happening? Like a log somewhere in the app that tells me when those features are paused or disabled?
