The image preview in Camera settings > Detection > Motion Detection > Activity Zones always shows an old/outdated still image captured many days ago. Judging by the timestamp, it looks like the camera remembers the image captured the first time motion detection was activated, forever or until the camera is reset. If I move the camera I cannot set new activity zones because I can't see what the camera sees. The app should automatically update this image when the activity zones page is accessed.

Edit: I just discovered a workaround. Go to the Cameras tab, then tap the "Play" button for the camera whose thumbnail preview you want to update. After doing this, the still image will be updated in the Activity Zones page too. This really should happen automatically when the Activity Zones page is opened. Thanks!
