If all your cams are assigned to CamPlus already, there seems to be a disconnect of updated data between the cam, the app, and the server. You might need to force a realignment of the three.
- Unassign the affected cam from Cam Plus in the Services menu.
- Clear the Cache in Account Settings
- Sign Out of the App in Account
- Close the App
- Long press the app icon, select App Info
- Force Close the App
- Restart the phone
- Full power cycle the cam (unplug)
- Wait for the cam and phone to fully reboot
- Log in, assign CamPlus to the cam and test.
