This is so upsetting to me, especially considering that my intro to the Apple ecosystem ~15 years ago was an iPod and how glorious that thing was.
Listening to my own local library has been a continually worse experience over the last 2 years. Not to mention, I use wired headphones with a lightning adapter 70% of the time, which somehow causes even more issues. Disconnects. Will refuse to play unless I unplug/replug or restart my phone altogether, increasing/decreasing the sound now has occasional lag that can take upwards of 5 seconds (and you have to unplug or restart to fix).
If I thought I had a shot of whatever job is in charge of this, I’d apply in a heart-beat just to fix all of this for my own needs.
