Xbox Game Pass Ultimate - is streaming on mobile or tablet working well?

Game Pass Ultimate will also allow streaming via Android devices, among other things. Does it work well with the cell phone when you are connected to Wi-Fi? Is multiplayer also possible over streaming?

It all depends on what kind of line and what kind of connection you are connected to the Internet.

The faster the line, the better and smoother it runs.

In order not to amplify this a bit you should be in a 5Ghz network, and an Xbox controller should be used.

To the multiplayer:

Yes, it works, but it is often not recommended because you have a higher latency with a slow connection.

Okay, thanks for your answer.
