After updating to iOS 10, most of the songs in my library that I could play before now won't sync and the error message I get is
Some of the items in the iTunes library, including "Song name", were not copied to the iPhone "iPhone name" because they cannot be played on this iPhone.
But I could play these items before, nothing has changed.
When I check the media format of one of the items it just says:
- kind: MPEG audio file
- bit rate: 320 kbps
- sample rate: 44.100 kHz
- channels: Joint stereo
- encoded with: LAME3.99
- format: MPEG-1, Layer 3
From what I know this is just an MP3 with constant bitrate, a format that the iphone did support one week ago...
