One purchased song not syncing to iPhone
I have one song, purchased from iTunes, that has suddenly decided to stubbornly refuse to sync to my iPhone (despite having been synced before). I have tried - deleting the file and redownloading it; desyncing and resyncing playlists that the song is on; editing the metadata of the song by adding a comment; syncing the specific artist and album to the iPhone; clicking and dragging the song to the iPhone. It just won't go on there. I'm at a loss.
iPhone 15, iOS 18
