Great news, sort of. Thanks for checking. I had contacted Apple by phone in early October and they first blamed the problem on my TV and then second on the apps. Clearly it is an ios problem or firmware problem or lack of communication with app developers problem. Looks like they now think it is firmware.
Until its fixed if you're desperate and if you have an iPad on 15.7 or alternatively buy an old refurbished iPad, iPhone 8 or SE (about $150 on Amazon), download all the streaming apps and use it with the HDMI adapter while using your real phone as a hot spot to connect it to the internet. You just have to make sure the refurbished iPhone has ios 13.4 - 15.7 on it (Hulu requires 13.4 and Pluto 13.0 and Peacock 13.?). I'm doing this with my iPad that's still on 15.7.
