I have resolved this problem.
I have found that on going to Mode Settings on the App the Disarm settings appear to be set to Motion detection and Live view. I turned these two functions off and the Disarm function now works as expected.
This morning (15-May-2020) at 06:00 I disarmed my system using disarmed mode as I have been doing since this new feature came out. I let my cats out and immediately got a detection warning and a chime from my ring chime. I checked the mode and it was 'Disarmed'. I toggled to 'Home' and back to 'Disarmed'. I still got detection from my animals. I rebooted the backyard flood, still got motion, so I toggled all three modes, but I'm still detecting motion and getting a chime from my ring chime. Arrrr!! I powercycled my phone, toggled to 'Home' and back to 'Disarmed' and I'm still getting detection. Arrrr!!!! I checked the Disarmed Mode settings and even toggled each zones from disabled to enabled then to disabled again. (Yes, I saved the settings each time). I'm still getting detection. Can someone help me please.
Mine is doing the same thing, it will not enable Disarmed Mode. I have toggled back and forth between all three modes and Disarmed will not enable.
Hey neighbors! If your Disarm mode is not working, could you please try removing the Ring app from your phone, rebooting your phone, and then reinstalling the Ring app. From there, re-log back into your account, ensure your Modes settings are as they should be for the Disarm mode, and then close the Ring app after putting yourself into the Disarm mode. From there, please walk in front of your devices to attempt to "set off" an alert. In the event that this still happens, I would love to see a screen recording of this to show to my team. What the screen recording should look like is you pulling up your Ring app, putting yourself into Disarm mode, then closing the Ring app, walking in front of your device (be out of sight before going near device during this test) and then set off the device so that it sends a push notification to your phone for motion detected.
This will show that even with your system Disarmed, the device is still recording motion and sending you an alert. Having this will be what I need to get this matter escalated up further! In addition to the screen recording, please reply with a screenshot of how your Disarm Mode settings are like @tlamy has, and what type of phone and OS version you have that you're running.
After about 10 days of working perfectly my new Ring Spotlight (wired) started ignoring my change to Disarm Mode as well as well and it now keeps alerting me when I am working in the yard. I did not make any changes to the app since setting it up. I will try uninstalling the app and will then reinstall as per your suggestion Chelsea and let you know if this works.
