In a possibly related scenario on my Samsung Note 20 Ultra, music folders that contain single FLAC/CUE files occasionally don't register as full separate tracks, just one big FLAC file.
To remedy this I have to do a full rescan via settings.
Occasionally I've found music folders that are completely missing the FLAC file, but contain the CUE file and associated artwork scans....the FLAC file just disappeared!.....then I have to download the whole folder again.
The real solution to this issue is to use CUE SPLITTER and just permanently separate the tracks from the FLAC/CUE files.....then delete each originating FLAC/CUE file.
Hope this helps!
