There should be device hand-off
There was a question about the pronunciation function (https://www.reddit.com/r/AppleMusic/s/VcGkyZu7VF) and it occurred to me to see if it was available on the Classical app where it would be useful for practicing opera arias. At the time I was listening to something on my phone.
As soon as I opened a song in Classical on my iPad the phone playback stopped and a message popped up prompting me to upgrade to a multi user subscription.
That the apps are connected on some level on different devices tells me that hand-off — having your current playback available on all devices is possible, Apple’s just not doing it.
That almost makes me mad enough to switch back to Sp*tify.
