Just recently an app is incredibly slow to load/sometimes doesn't ever load.
Looking in the App Details (on Android phone) is shows Sharepoint with 4 purple dots, indicating loading or logging in...this sometimes keeps going.... Checking other apps they all have a tick box and say signed in....
This a bug/issue/known about?
