In preparation for the release of WASM on Xbox support and Sim Update 12 on 3/21, the Xbox WASM add-on (Microsoft Flight Simulator: Add-on Support) will be updated on 3/20.
WASM on Xbox support will be enabled on 3/21. You do not need to install or update Microsoft Flight Simulator: Add-on Support before 3/21.
Beginning on 3/21, Microsoft Flight Simulator: Add-on Support will automatically install or update to the latest version when Microsoft Flight Simulator is launched on Xbox.
Thanks,
MSFS Team
