Why do I keep receiving invites for minecraft windows 10 edition from random people even...

Launch Minecraft for Windows 10 from your Start menu or desktop.
Click Play.
Click the Edit button next to your Realm.

Click Play. Click the Edit button.

Click Members.

Click Invite next to any people already in your Xbox friends list.

I hope this is helpful.

Looked through some of the help articles - man the information is confusing.

Anyways from what I'm inferring from the posts is that you can play Windows 10 to Windows 10, and Pocket Edition to Windows 10 and that's it right now.

"You can play Minecraft: Windows 10 Edition Beta with other devices running Pocket Edition, such as Windows 10 and Windows Phone devices. Right now, you can play local multiplayer on Minecraft: Windows 10 Edition Beta. Soon after the launch, online
play will be available for Minecraft: Windows 10 Edition Beta."

Can I play online with other people on Windows 10? Or on different devices?

You can play with up to four other people running Minecraft: Windows 10 Edition Beta or Pocket Edition on your local network. You can also play online with up to four of your Xbox Live friends in online multiplayer gaming.

Hey there! You're going to need to verify which version of Minecraft you have. There are two on the Xbox One that you could have.

Minecraft: Xbox One Edition is no longer supported. It's playable, but it can't be found in the Store and does not receive updates. This version of the game does not have Realms access.

Minecraft/Minecraft: Windows 10 Edition/Minecraft: Bedrock Edition (All just different names for the same game) is the version with Realms that are cross-compatible.

Java version (only available on PC) is not compatible with Xbox.

If your child's friend has the Realm set up on the correct version of Minecraft, you just need a Gold Subscription. Realm hosts pay the monthly fee to keep the Realm online. The friend will need to invite your friend/add them as a Realm member from their
Xbox or PC, then your child will receive a little envelope thing on their Minecraft menu. That is the Realm invitation. Once that's accepted, they should be able to join the Realm.

I bought the Windows 10 version of Minecraft by mistake, but the one I wanted was the java edition.

I saw that anyone who buys minecraft java edition is entitled to minecraft Windows 10. Is the reverse also true? Who buys minecraft windows 10 is entitled to minecraft java edition?

If so, how do I access the java edition version at no additional cost?

I don't even have Minecraft Windows 10 Edition. I only have the PS4 Edition.
