I have a macbook air 2015, updated to Monterey and can't find Airplay which I've used to mirror to my Sony Bravia TV. TV is set with bluetooth. Mirroring is on on the laptop. still can't find Airplay or when i tap mirroring it just gives me this.

Hi johnyankeedakota,

It sounds like you're having trouble with AirPlay and we can help.

You said you get Screen Mirroring, when you click that do you see your TV available? In the article you came from, did you take the steps to turn off your TV? Make sure you restart the TV entirely, sometimes displays will have a sleep mode that doesn't entirely restart the TV as you would need to.

Try restarting all the devices involved in the sharing and taking the steps to mirror your screen as seen here:

Use AirPlay to stream what’s on your Mac to an HDTV

Thanks for using the Apple Support Communities.
