We are working to make the app compatible in the very near future. Until then, please refrain from updating your device OS to Android 10 if you would like to use the Companion App at this time.
We will provide an update once we are able to determine a timeframe for Companion App to be compatible with Android 10.
We apologize for any inconvenience this may cause, and thank you for your understanding and cooperation.
