Apple Music language change
I've always had iPhone language set in English. Once in a while, I realised that in order to get my Maps assistant speak Russian I had to switch iPhone language to Russian (weird enough, Apple devs, that this settings isn't interconnected with Siri language). Well, for a matter of a test I switched iPhone language to Russian, then I found out how bad Maps are (indeed, even worse) and gave up the idea to use them with my CarPlay function. I reverted language settings of my iPhone back to English, by my Apple Music seemed to stick with Russian since then. Nothing helps:
1. Reboot
2. Change AppleID and AppStore language settings
3. Re-sync iPhone with Mac where everything is in English
I've read a lot of threads here (some of them older than Apple Music), but all of the users gave up, saying it's not possible to have a region set to one country and have another language in UI. You're wrong, guys! It worked for me for about 5 years! Give it back to me, you, curvy hands of Apple developers!
