It can be a time consuming process however since I need to find the relevant file in the correct folder, remove from the Plex Media folder, then open it using Mp3tag and delete the cover before I replace the file into the correct Plex Media folder.
It seems as if I open the music file directly within the Plex Media folder, and remove the cover art while the file is still where it should be, Plex do not see that the cover art is removed and hence do not replace it.
I have tried to refresh the metadata and scanned the library files but it will not fix the issue until I follow the procedure described above.
If you should happen to know why and how I can correct this I’d appreciate some tips on this as well
