We are attempting to push out the Android app to a fleet of tablets running Android 9 and other near versions.
They're all running over a cellular network for data access.
The problem arises when the tablet is inactive for a period of time, at which time the guest will appear offline and you cannot connect remotely. to access the tablet again there needs to be manual intervention to open the app and wait up to 10 minutes for the app to attempt connecting to the server.
I have been speaking with support with ticket number #14906943 and they have requested I post this here.
Android version 9
