Users are reporting that Explorer requires them to sign in each time they use it. Meaning that they need to authenticate on the ArcGIS server secured service on each use (this is not the sign in to our AGOL org). Does anyone have ideas about what might cause this? My understanding is that once a user has authenticated and assuming the app is not closed, they should remain signed in.
Users are either in our fire stations on wifi or out in the field on cellular, and may go back and forth between those modes multiple times during a shift.
This is for iOS. Most users are at latest version.
