I have unlucky enough to have an AndroidTV which does not support Disney Plus. It does not appear in the app store, and when I load it on my phone and attempt to cast, I just get an error message that the app is not supported (which is weird, since I don't want to use the app, I just want to cast.)

So, I know want to know if the claims on the Disney Plus website are true: If I purchase a Google Chromecast HDMI dongle and use it, rather than AndroidTV... would I be able to cast Disney Plus from my phone to my TV?

If so, is there anyway to "dumb down" my AndroidTV's casting and just do it like the Android dongle, which works?

Sorry if all that is confusing, I just find it wild that the play store that my AndroidTV has can't install Disney plus, and even weirder that I can cast to Chromecast Google dongle and have it work, but not Chromecast Android TV. Any help or confirmation would be great. Thank you and Happy Holidays!
