Love the service... but not happy that I continually have to clear cache/storage (aka uninstall/reinstall) to recognise USB DAC (Dragonfly Cobalt) and receive the prompt for exclusive control to bitstream to the device each time. If I don't do that, it defaults to Android mixer and I get the "blue" 24/48kHz indication instead of that lmagenta MQA or even a solid green 16/44.1kHz. Looks like it's back to UAPP. At least that works consistently and doesn't deafen me on an initial volume change.
