The Hubitat app works perfectly every time while at home on WiFi (local). If I leave home or disable Wifi while at home the app hangs when phone data is cellular:
Stuck on welcome screen
OR
'Dashboards' and 'Lights/Switches' endless spinning logo or blank white screen
Sometimes (not always) after 30 seconds to several minutes “Hub Unavailable” is displayed. On rare occasion after several minutes 'Dashboards' and 'Lights/Switches' eventually display but don’t work. Screen shots attached. I tried clearing the apps cache but no help. When I return home or re-enable WiFi the app works perfectly again. When phone is on cellular data (not Wifi) I can temporarily get the app working again by:
Power cycling phone, WiFi still disabled after power-up
OR
Uninstalling app then re-installing
