Settings changing

Am I the only one that has my settings changing them selves periodically ??
One my cams that I have the alerts muted on will all the sudden start sending alerts, then for some reason some of them will have the sound turned off. I can set everything back to how I want it and it will last for awhile but then they do what they want again. Any ideas??

Possibly periodical updates resetting to default.

I dont have auto updates turned on and just now all of my cams had sound turned off again
