Minecraft says I can't play on realms because of account permission issues

Hi Stinklemcruitl00ps! My name is Ricardo an independent advisor ready to help you with this situation!

Of you are not receiving the verification code on the mail, be sure you are writing the correct email address to receive the code, this code will only be received if you write the email that is covered if it's written correctly

Thank you for your reply. All privacy settings have been verified and are set to “Active” or “Everyone” so there should be no barrier to multi-player games and join groups.

The problem is not that I can’t join a specific Realm. It’s a general problem. Under Play, Minecraft says says “You need permission. You cannot play on Realms because of how your Xbox Live account is set up. This can be changed in your privacy & online safety
settings on Xbox Live."

When I log into Minecraft for windows 10, it says that there is an error with my account. I can't go into realms, friends worlds, or servers. Maybe it is because I switched the email on my Microsoft account recently?

Hi Alex,

Thanks for reaching out to us in the forums for this issue with Minecraft Realms on the Nintendo Switch. Based on the message you received, it may be possible that your account doesn't have the correct permissions to access online multiplayer across different
devices.

Is your account a child or adult account? Players under 13 years old will have online multiplayer disabled by default with Minecraft and
won’t be able to join Realms or servers unless a parent changes their account settings.
For help with changing these account settings, you will need to change your
Privacy and Online settings of the Xbox Live account.

I hope that this information helps out!

You have registered your "main account" as child account (under 18+ of age) this is why you are not able to play online and Mojang support suggested you to set up a different account

Unless your parental account gives permission your child account will not be able to play other realms in Minecraft
