Can no longer play/stream music from Apple Watch speaker
I recently I discovered that I am no longer able to play music on my Apple Watch without being prompted to choose a bluetooth device. Previously I was able to choose Apple Watch as my audio output which is no longer an option. If I attempt to play music with my iPhone turned off, I am forced to choose a bluetooth device. Also, I can connect my watch to a bluetooth device and play music (iTunes), but when I attempt to stream Pandora, the audio output defaults to my iPhone despite being "connected" to the device. If my iPhone is turned off, I cannot play any music from Pandora. Once again, I can play from my iTunes library, but Pandora is not functioning the same way.
Can someone please tell me how to fix these issues?
Apple Watch Series 3, watchOS 7
