The first part of your item was very helpful — thank you. I will try it. The second part, asking for photo/video is obnoxious — suggesting that you can’t trust our relatively straightforward descriptions of what happened. Enough people have complained about this no one at Ring should doubt that there is something seriously wrong.
In my case, Modes was working perfectly until yesterday, 15 May. Suddenly, the Disarm function stopped working properly. I hit the Disarm button and Ring reacted normally, switching the indicator on the Dashboard, and delivering a Notice that the system was disarmed, time, date, etc. BUT, the system was not disarmed. All cams generated motion alerts as if Ring was in Away mode. I use iPhone 6 with the latest iOS.
