i’ve used her phone to control music on long car trips, if there are differences i haven’t noticed. again, anecdotal.
I restarted my phone, reinstalled the app, went through several iterations of iOS updating, the problem never went away. No other app, including Spotify, has this issue on my phone. After a month of paying for Apple Music without Classical working I shrugged and unsubscribed. Big loss for me, and for them, since I am exactly their target audience with Apple Classical.
Some people are complaining about Spotify UI/UX but at least they provide a lot of features and it works pretty well most of the time. I find the app more responsive and just overall better has a streaming player.
I subscribed to apple music for 5 years but then I just switched back to Spotify this year. It is just better.
