Motion detects x3 were offline for 3 weeks, no notification?

Don’t arm Ring much, but went to last night and it said something like “3 devices are offline want to still arm”I came back and it was 3 motion detects, 2G ones. Today I removed and refitted batteries and shows full battery and connected fine. My problem is why haven’t I been informed via notification, email that I’ve had 3 devices offline for 3+ weeks. I looked in history and it’s offline from 2nd Nov. Agreed it told me when trying to arm, but I’d prefer to know beforehand as I didn’t have time to fix then. Looking in history the base had a disconnection on 1st Nov, I had to unplug and remove batteries as it froze. Then later these 3 motion, I have numerous other motion and contact that were ok though.
