When using ArcGIS Field Maps on Android 11, you may not be able to access the device’s external storage when connecting it to a computer. The files stored externally on the microSD card still exist, they just won’t appear in the computer’s file explorer. This prevents copying (sideloading) mobile map packages (MMPKs) and basemaps to the device.
