The last two security updates of MacOS Big Sur have cause my sync settings in Apple Music to reset (from sync checked songs to Manual) and when I change the setting back to manual, Music says it must remove the library from my IPod classic to sync the new library causing days of resyncing from scratch. Has any one encountered this problem and found a way to address it? I would like to stay on Big Sur as long as it is getting security updates, I have software that only woke up to Big Sur such as Ivolume for song volumes.
