For some time I have had an issue with my Smartthings Android App not working properly when my phone is not connected to WiFi. In particular I use the app to control two separate locations, but when on mobile data I cannot change location. Selecting the drop down by location name in the app simply leaves a message “Loading” on the screen and the choice of the other location never appears.
Other Apps work fine on mobile data and the signal is strong
I have tried uninstalling, reinstalling, clearing cache etc, but nothing makes a difference.
My phone is a Sony Xperia XZ2 Model H8216
Android version 10
No Data Saver or VPN used.
Smartthings App ver 1.7.91.24
I would be grateful for any assistance.
