I have a Sony 2020 Ah8 and cannot locate the Apple TV ap in my aps?

• Looks like you need Sony A8H Series (2020)2 but that model is for Air playing to ,

For Smart TVs

• See a list of supported models
• Update your smart TV to the latest firmware
• Install the Apple TV app from your TV's app store

Devices you can use with the Apple TV app and Apple TV+ - Apple Support

The Apple TV app for select Sony TVs is said to be released “later this year”, probably through a software update rather than a general item in the app store.
