Show your blocks.
- Which Android version?
- With which app was the ASD created and
- with which app do you (try to) open which ASD?
- Companion or APK?
The ASD (App-specific Dir) is:
/storage/emulated/0/Android/data/<packageName>/files/
This means each app has its own ASD.
Btw, on Android 11 the ASD is no longer visible
(unless you are using an external file manager, such as Total Commander).
