The “Black Recording of Death” has struck my Ring Doorbell 2. RSSI is -34 so connection to router is pretty good. Using the Android app and the PC Dashboard app give the same black recorings for motion detected notification. However, live viewing works fine for phone or PC Dashboard, so it’s not a router problem. I’ve gone through all the highly tecnnical solutions suggested on this site, and No Joy. Someting’s wrong either with Ring’s servers and/or their software.
This problem is NOT SOLVED!
