I have the same problem on my S21 ultra 5G, build OneUI 4.1. No SmartThings panel anymore, can't switch audio output between devices. Edit: So basically while BT is connected to any audio device, there is no option "This phone". Same in Spotify settings, no This phone. So now when I'm in my car and the kids want to watch something on my phone I have to turn off Bluetooth on my phone, and naturally that disconnects my watch, this is not ok it this is by design.
Missing this feature after the last One Ui 4.1 update. I'm fully aware that this can be achieved via Media Output (very inconvenient since it's essentially launching another application) and the overly bloated quick settings (they are far from being quick if there are too many). The Audio Output toggle was a very convenient way of doing the task, since it was a persistent and easy to reach notification.
