Ring security devices all offline after brief power glitch

After a power outage of a couple of seconds overnight, both keypads on Ring security disconnected during the night. I was able to arm and disarm in the app. In the morning, ALL the other devices (extenders, sensors,detectors) went offline in sequence. I have cellular backup with extra data and two fully charged battery packs. The system was installed 2 months ago, all new equipment. All tech support could say is it might be software related. Had to remove all devices, take them "close to base", remove z wave, factory reset every piece (which has to be done through the app, which none of the documentation clearly states). This is utterly ridiculous. If I had been away, the house would have been totally unprotected for the duration. Why doesn't this system automatically reset and reconnect when it has battery and cell backup? This needs immediate attention from someone who actually knows how to program.
