I plugged an SD card via adapter to my Galaxy S21 Ultra. I added the music folders on the card to Poweramp's music library, and if I use an Android file explorer to open music files with Poweramp, it works.
But Poweramp doesn't show the music folders I selected under "Folders Hierarchy", and I don't think the folders are being scanned at all.
How can I get Poweramp to show these folders in its "Folders Hierarchy" view?
