As of August 2021, there is no apparent way to access Mapillary photo storage on the Android device (via USB cable).
- Mapillary Android app version 5.0.5
- Operating system: Android 10 QPIS30.73-33-9
- Phone model: Motorola One Fusion+ (XT2067-1)
Please let me know if a solution for this exists (without rooting the phone).
