Why is my iPhone app and Firefox browser not playing to my Xbox 360

Are you able to cast to any other device? The XNox 360 is an older client and hasn’t been updated in a while. I’d like to narrow down if this is a iPhone/web issue or an XBox360 issue.

Yes, I cast to my Chromecast Audio. The issue is with the xbox360. It used to work.

Yes, I cast to my Chromecast Audio without issues.

Ok, thanks. Still investigating.

I just bought a Samsung Smarthub TV and the Plex app is doing the same thing as my xbox360.
