Hello,
I've run into a small issue with iOS 13. VoiceOver continues to sound through my phone's internal speaker rather than the connected Bluetooth speaker, but music works as expected.
My first thought was to check the audio destination option in the rotor, but that doesn't appear. I can't ever recall a time when that worked. I was wondering if any of you have had the same problem. Maybe it's a bug, or maybe there's a setting in iOS 13 that I need to change.
