Again, all I can point to are the instances where I was playing music via Spotify on my Alexa devices and thanks to Spotify connect when I connect my headphones, Spotify starts playing automatically on my headphones. The downside is that occasionally Overcast stops playing because Spotify wants so much to take over and start playing. But it’s hard to say if that’s an iOS beta thing. Similarly, the app still ships for iOS 12 right now, it’s possible the iOS 13 version of the app will have a clearer explanation for the use of Bluetooth.
