not able to log into apple tv app on sony tv

Hello babsio,

Thanks for using the Apple Support Communities!

Could you please confirm what exactly you're seeing when attempting to log in to your account? Do you see a particular error message?

Are you able to log in to you account on other devices as expected?

Does the TV app have any available updates?

This link can help with updating: If you can't watch or stream movies and TV shows in the Apple TV app - Apple Support

Cheers!

Specifically for Sony TVs, it may have to do with the TV’s privacy settings. Try this:
