Receiving beta versions of Minecraft, but I'm no longer participating in it

This is an issue that many people are facing.

Hi !

If you have a Beta version of Minecraft, I think you can only join people with the same beta version. Maybe your others friends can't be joined because they don't participate to the beta program.

Regards

In addition to checking your connection, see if your friend participates in the minecraft Beta and if you have the same upgrade version.

The Xbox 360 Edition is currently based on the 1.6.6 Beta version of Minecraft on the PC. The PC version is currently in the 1.2.5 full game (no longer in beta).

Minecraft earth closed beta

Here are a few important details about the Minecraft Earth closed beta:

• The closed beta will launch for iOS in the next two weeks, with the Android version following soon thereafter.
• As with most closed betas, the number of participants will be limited in numbers and locations. This is to make sure our servers are able to keep up with all the exploration, creation and, hopefully, surviving that is going on around the world. To learn
  about the current availability of the beta, ​follow Minecraft Earth on Twitter​!
• As is also common with beta versions, your progress will occasionally be reset as we test and develop various features of the game.
• If you are selected to participate in the closed beta (congratulations!), you will receive an invitation email to the email address you have associated with the Microsoft Account or Xbox Live account you submitted in your registration.
• If you are selected (congrats again!), you will need to play at least once every 7 days. If you don’t, we’ll give your spot to someone else, as space in the beta is very limited.
• You have to be 18 years or older to participate.
