I have a strange issue. When I open the Smartthings app and the phone on 4G all devices report offline. When I open the Smartthings app and the phone is on Wifi and conencted to the same network as the Hub all devices report online.
I searched but cannot find any setting that should control this. Why does the Hub report all devices offline when not connected on the same network?
I am using the new app on a S9 with Android 10 and latest updates
