How to join phase two of Minecraft preview

lol I dont even know how to play fortnite. Fortnite will eventually phase out just like minecraft.

The xCloud still on the preview phase, if any word we keep you updated

The "outdated client" error only comes up when a player is trying to join a world that is in the Xbox Insider Minecraft Beta preview ring. That's a mouthful, I know. This version of Minecraft is the Bedrock/W10 version but it just gives your Minecraft updates
more often.

Two scenarios could be true. Your friend is the one on the newer update provider through the Insider Program, or you are. If its your friend, they need to deselect the Minecraft preview ring and "revert" to play with you. This temporarily locks them out
of any world that is saved in a newer update until the public version receives that update. If you're the one in it, you need to deselect and "revert." You could also try looking up the "Xbox Insider Hub," joining it, and then joining the Minecraft beta in
order to play with your friend.

According to what's mentioned in the link below (section: Essential information before participating in a Minecraft Beta), you can't switch back and forth between the two programs. You can find more information about this in the following link :

You'll need to create a new thread in the forums linked above asking to remove your console if you cannot do so from the beta dashboard app.

Be aware that if you do request to be removed during a preview phase you will continue to receive updates until the current preview phase has been fully released to the public.
