I have an Android 11 device with an SD card (also a Galaxy S10e). Similar to Nummer378, the app has the permission “Allow management of all files”, and I was able to grant it access to a folder on the SD card.
For me, as I posted here, scanning is very slow for files on the SD card since upgrading to Android 11. It is still pretty quick for the phone’s internal storage.
Is the slow scan on SD cards likely to be something we’re stuck with?
