It was working good for a while and then I tried to add a new device and it freaked out the app & now I'm having to fiddle with it to get it back up and running. also one of the doorbells fell off of its magnet because ring doesn't use good quality adhesives. because it's popular it's common, is a desirable target to hackers & Google can make any bored neighbor a hacker. I will re-rate when I get my ring app repaired. . How much trouble will that be?
