I use the monitor as a large screen attached via USB c. So refresh of 60hz
If mac is connected via HDMI then refresh is 30hz — unsatisfactory but prob ok for my Apple TV box
Now anything that connects to these sources can use the display
I do not use the native screen IOS probably Android directly

Unfortunately, I don't see the full question. As far as I know, Airplay is an Apple product / technology. Unfortunately, I can't say anything about it. However, you will certainly find the information you are looking for on the Internet or directly from SAMSUNG.
Another tip: I would never trust a statement and make a purchase decision based on such a customer chat and customer feedback.
