I heard that you can get Unturned Beta from the Xbox Insider app. I cant see it in there....

You can either join the Insider Beta as well and get the 1.13 beta, or you can ask your friends to leave the beta, uninstall Minecraft, and re-install the official 1.11.4 version.

If you wish to join the Beta, you can open the Windows 10 Store, and search for the Xbox Insider App.

Install the App, and sign in.

Under Insider Content you should see the Minecraft Beta. There you are able to join.

Xbox console system version for if you're on the insider build. But there is also a Xbox Game Pass (beta) app you might want to download and try? See if that's any different?

With Xbox pass beta it worked from a different device, then from my main one I can still see the default Xbox which I slected. Thank you.

Fyi, the Xbox version is 10.0.18362.5047 (19h1_release_xbox_dev_1907.190628-1920)

Hey Aníbal

Thank you for taking the time to post this on the Xbox Forums.

In regards to
accessing Minecraft Betas, you would have to first download
Xbox Insider Hub on your respective platform.

Once you have that installed, this app, you can then launch the app, and navigate over to
Insider content, and you should see the option for Minecraft Beta.

You will then see the option to "Join", and it should install and let you access this from in the game now.

I will further break down these steps here:

1. Go to the Store app on Xbox One or a Windows 10 PC.

2. Search for the Xbox Insider Hub app.

3. Download and install Xbox Insider Hub.

4. Launch the Xbox Insider Hub.

5. Navigate to Insider content > Minecraft Beta.

6. Select Join.

7. Launch Minecraft!

Give this a try and let us know if this works for you!

If you're enrolled in the Minecraft beta you need to unenroll from the same (you can unenroll from the Xbox insider app)

You would opt into the Minecraft Beta via the Xbox Insiders App. Unenroll your device, via the Xbox Insiders App, from that beta test and it will START the process to remove you from the beta. This can take sometime and might require the updates to cycle
through the next release, catching the full release up to the beta versioning before you are fully unenrolled and able to access the full release again.
