Well Amazon Music/CarPlay has bit the bullet. The app opens but when try to play something it closes the app . If you tell Siri to play something it will play but the display is blank. The "multiview" where maps, calendar, and now playing are, shows the song and controls. Tried the delete/reinstall, reboot blah blah. Also downgraded to beta 2 and didn't help. Its been fine on 26.0, 26.0.1 and 26.1 beta 1 and B2. Now its borked 🙁 . Apparently its a common issue currently. Maybe B4 or an Amazon Music app update on the horizon to help. If anyone has resolved it somehow, appreciate the info if you share how you did. 🙂
