Over the last few days all of my camera have stopped capturing snapshots. It didn't happen all at once. First one, then another, then all. I have a Ring doorbell (battery), Ring Flood Cameras, Stickup, etc. Worked well until a couple of days ago.
On 2 out of 3 Ring products it is working. My Ring DoorbellII still has the problem. Support was very helpful although it was the normal reboot, hard reboot, reconnect etc. They are sending me a new doorbell. Suggest you contact support.
