Hey @daleengle. Just wanted to clear this up for you! For the new Modes feature, this is only for the Doorbells and Cameras to have motion detection disabled/enabled or Live View disabled/enabled. You can customize these depending on the mode you are in. The new Modes feature cannot be used to snooze your chimes, but if your camera is not detecting mode, it will not be alerting your chimes, so you can set your cameras to not detect motion and therefore would not alert your chime!
The error message that you are receiving is in relation to your Ring Alarm system. Since you have both systems, changing to Disarm/Home/Away will now affect your cameras AND your alarm. You got this error message when trying to change modes because you have a door or window open, and when you try to arm your system in Home/Away mode. Please make sure you have all of the doors and windows with contact sensors closed when you are trying to test this out to see if it fits your needs!
