Does not work xCloud on Samsung Tizen OS 2021, gray background and error.

Hello, first it's a pleasure to be able to help you today.

My name is welcome to the community.

Hello Faust, they added support for 2021 TV`s recently so there may still be some issues.

On TV, as it has a very simple structure, try to uninstall the App and also check if your TV system has updates, and then install the App again.

My TV runs samsung proprietary operating system called Tizen OS. Yes the controllers and the TV and the APP are compatible

Hi Afnan. My name is Kyle and I'm an independent advisor.

This is likely because Xbox Cloud Gaming is not available in India. See this link to check the supported services in your country: https://www.xbox.com/regions

What sort of TV, brand and model, is your TV? I have the Xbox One X and a Sony 43' KDX8000E series 4k HDR TV (which is a 2017 model from Sony), and have no issues. But have HDR mode on Auto as Full HDR10 mode is too powerful but is better for producing better
blacks somewhat. My TV has an X-Reality Pro processor and advanced Tri Luminos colour technology with wider colour palate and natural colours. Samsung TV's have a bad OS which has serious security vulnerabilities from my research. Android OS on my TV is more
secure and is updated more frequently.

through your room windows.

Yes you can get cheaper 4k HDTV's but those type of TV's don't have the same QUALITY as more pricier TV's.

Well there is two problems

First and.foremost Samsung tvs don't use android or Google play services it uses tizen which is not compatible with Google play services

You need it for Android xbox app
