After my two CCwGTV4Ks upgraded to Android/Google TV 12, clicking on any Hulu Stream Link results in an error saying there is no app installed for that action. Disney+ Stream Links work as expected, so it is not a global Stream Link issue. The exact same Hulu Stream Links work as expected on Android Phone 12 and Android/Google TV 11 (TS4K+). All devices are on the same versions of Hulu and Channels, so the issue is definitely only with Android/Google TV 12.
Did the Hulu app upgrade recently too?
Not that recently, November 2nd. All of the devices are using that version.
This is now resolved:
