For the Flightsimmers who are willing to test out the new Sim Update 1 (v1.3.7.0) – You can join the beta test. The Sim Update 01 Beta is now available on Steam, Windows PC, and Xbox.

Please find instructions to join the Sim Update 01 Beta here on the MSFS Website.

And more info on this forum topic.

Read also the warning:
“There is always a risk that you may have to re-install the sim when joining/leaving a flight, so please keep this in mind before participating.”

Please remember if you decide to join the Beta and install the build, you will likely have to re-install your sim if you wish to leave the Beta before it ends. If you did not opt out of the last Beta, you will automatically stay in this Beta and receive the next build.

In addition, while in Multiplayer Mode, you will only see users who are in the same build as you.
