I use the feature almost every day. Airplay only works with certain newer TVs. Ive been to over 300 hotels and airbnbs in the last 5 years and i can tell you that the majority of them dont have Airplay. Even if it is a smart tv, i prefer using my own log ins from my ipad, and the only way to connect that is with usbc to hdmi. I used to travel with an Apple TV, coz i also prefer airplay, but it’s more work than just connecting the ipad or iphone. A usbc iphone, not having a normal, to be expected usbc feature, should be mentioned somewhere. I think the majority of android phones with USBc can connect to an external display. I get the feeling we are going backwards. iPhones should have a stage manager and full external display support, not going the other way.
