Electronic Arts (otherwise known as EA) is working on allowing players connect across multiple platforms and is testing cross-play functionality on the PlayStation 5, Xbox Series X|S, and Stadia versions of EA SPORTS FIFA 22
This makes it possible to have a wider pool of competitors that you can play against without the platform being a barrier.
This was shared on a dedicated post on the FIFA 22 FAQ pages was shared on the official FIFA Direct Communications account, this page notes how the cross-play feature will work and how you can opt-in or opt-out.
What is this Cross-play test?
For FIFA 22, Cross-play is the ability to play the game with players from different platforms. The Cross-play test will be available in Online Seasons and Online Friendlies for now. This means you can choose to play FIFA 22 with a friend on another platform, or climb the Online Seasons Divisions against players potentially playing on other platforms.
The Cross-play test is limited to Online Seasons and Online Friendlies for now so as to reduce the chance for introducing new issues into the game. Based on the feedback and data from these two modes, this will assist EA on how Cross-play could further be implemented in future titles.
How to enable the Cross-Play Test
Once activated and you are in the main menu of FIFA 22, you can find a widget in the bottom right hand corner that can be opened with the corresponding button prompt, as pictured below.

From this widget, you can simply follow the button prompt to enable or disable your Cross-play test participation. In this widget, you can also search for friends regardless of their platform. Once you have found your friend’s name, select them and choose the option to add them as a friend. Your friend should accept your request in the widget.
You can also block and/or mute someone if desired.
You can also control your Cross-play test participation by visiting the Matchmaking Options Settings screen, as pictured below.
