Kind of odd but just noticed this. Am watching the Tenn/KC game on my computer. Just checked the Settings page and found this:
Watching ch810 from V40 ThinQ (Remux Running at 1mbps: 1h21m24s @ 1.00x (60.01fps)): strength=100% quality=100% symbol=100% rate=6.3Mb/sec buf=0% drop=0%
It shows my phone (bolded) as the playback device.
