Long time user, first time poster. First off, thanks for all your hardwork! This is by far my favorite music app on Android and I've been using it for years now across all versions of Android. Since Marshmallow scrapped set mountpoints for external storage, my microSD card is being dynamically mounted on boot as /storage/public:179,65 It actually shows up fine in Poweramp under Music Folders, but after I select a sub-folder (or the entire storage directory), it doesn't "stick" or save. When I return to Music Folders, no sub-directories in /storage/public:179,65 are selected. If I were to guess I would assume it has something to do with the directory containing a colon or comma? I can't say, just my hunch. Let me know if there's any additional logs/debugging I can do, I'm a developer myself so I'd be more than happy to help out.
