- You will not have access to Realms and will not be able to join non-beta players while you’re previewing the beta
- Any worlds played while in the beta cannot be opened in previous versions of the game, so please make copies of worlds to prevent losing them

- The beta is available only on Xbox One, Windows 10, and Android (Google Play). To join or leave the beta, see aka.ms/JoinMCBeta for detailed instructions.
