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?
