Lightning to HDMI adapter not working

Any resolution. My Lightning to HDMI cable quit working for video after upgrade to 16.2.

Same here.

Netflix says playing on tv and it’s not

Hulu plays video but no sound.

I can’t find the solution anywhere. I used my moms phone that hasn’t been updated to the newest iOS and hers worked instantly. So it’s not the apps problems, it’s Apple.

Did a complete new install of IOS but didn’t restore backup and it worked. Before reinstall the charge wouldn’t even work on the adapter, after it started charging and the hdmi worked fine

What was the fix?
