Does airplay work if tv is connected to your phones hotspot

Hi tinamarie240,

Thank you for using the Apple Support Communities! That's a great question. We see you were linked from the article "Use AirPlay to stream video or mirror the screen of your iPhone, iPad, or iPod touch". As noted in the article, both the iPhone and Apple TV or AirPlay 2-compatible smart TV will need to be connected to the same Wi-Fi network.

Hope this helps!

Have a great day.
