Multi device sync ?

I don't use my cell phone much. But I have installed the ring app on it as well as my samsung tablet (which I use a lot). All weekend long I was using the app on the tablet to try and iron out a working doorbell (that is still ongoing) - but today I picked up my cell phone and there were a gazillion motion alerts. I thought I noticed smoke as I cleared all the notifications from the phone :-) I did reinstall the app on my tablet this weekend and made sure I turned off motion alerts, but somehow the phone had motion alerts enabled. I have no interest in motion alerts. Yes I'd like to see motion events but that's it. So I wonder what sort of impact (unknowingly) the cell phone receiving alerts has on my overall ring doorbell experience ? Obviously in my case settings are not sync'd across devices. Should they be ?
