I just upgraded my phone. No matter how many times I do a full rescan or restart the phone or set "ignore short tracks to", the only MUSIC FOLDER options shown now are either NTERNAL STORAGE or SD CARD. No folders are shown and clicking anywhere on either of those two choices gives me ZERO files and folders. What am I doing wrong?
Androids 5-9 were stable in this regard, in Android 10 the paths changed due to (enforced by Google) the "new" Storage Access Frameworks (SAF) API requirement to access files.
For SAF you first hit that Enable button, find the desired storage and optionally a root folder and hit "ALLOW..." button. Depending on ROM, additional menu / Show Internal Storage selection is required + side menu should be used to select the target storage.
Poweramp then either uses default Music/Downloads/Play
