Mind just did it this morning. It was very strange as I monitor the battery (dual batteries) and usually replacement them both monthly. Then all of a sudden both batteries on the app show dead (and ring battery door open error). I R&R the camera probably 20 times with no improvement. For a moment there I though someone had taken the camera, but that is about 20 feet up so definitely a low probability. I am currently on the phone with Ring, but it has been about 10 minutes so not sure if I will actually get a live person. I just want to confirm that it is actually a software issue:(
I forgot to mention that I have a dedicated 1GB Modem and an EA9500 5 feet away from the camera (currently running 662mbps-down/19up/10ping so it is not a connection issue).
