Ring Pro doorbell seems to be rebooting after a button press/ring event

I have a Ring Pro doorbell, and wasn't able to view the video feed after a recent doorbell press. Reviewing logs on my home network (Fingbox), it looks like the camera is going offline for ~10 minutes about once a week, presumably after a button press. The inside chime is still ringing, it's just followed by the camera rebooting. When I open the Ring app, the thumbnail shows the person who rang the doorbell, so the doorbell starts uploading before the reboot (maybe from the motion as they walked up). I had a problem a couple of years ago, where the doorbell wasn't reliably ringing my mechanical doorbell, so I upgraded my transformer to a 30VA unit. As far as I know, the mechanical chime is reliable, it's just the doorbell rebooting that sometimes happens. While testing the unit, things worked every time, so this is definitely sporatic; I'd seen some alerts from Fingbox, but didn't pay that much attention, and didn't realize how often it was happening, until missing this today. I read some comments on the Ring community on Reddit, mentioning an internal battery that isn't user servicable. Anyone having similar issues?
