I manually manage my iPhone's music (iOS 11.1). I use music from my hard drive, not from my iTunes account. When I drag music to my iPhone, all metadata of my music shows up in iTunes (iTunes 126.96.36.199) correctly. But on my iPhone, an album is broken into individual albums. So a 12-song album is turned into 12 1-song albums. This is the case 100% of the time. Every time that I add any album to my iPhone, every song will show up as separate albums.
Also, the artist is missing from every song on my iPhone.
I am 100% sure that my metadata in iTunes is correct. Artist, Album, and Album Artist are all identical down to the capitalization and everything is correct on the Sorting tab. The Compilation box is not in play here. I have verified my song metadata with a 3rd-party ID3 editor.
The only thing that works is to delete the music from the iPhone and then re-add the music. When I re-add the music, the music now is grouped together and labeled correctly on my iPhone.
Can I fix this issue without having to delete and re-add the music onto my iPhone every time?
