I integrated my Mojang account to my Microsoft account, but then I can't play multiplayer...

Hi, I hope you're doing great out there despite the issue that you're experiencing. I am an Independent advisor and I am here to help you in regards to your concern.

If you’re a minor, you need to ask an adult to manage your account for you. Ask them to add you under a family group via https://account.microsoft.com/family as a member. Once done, ask them to sign in to https://account.xbox.com/settings to manage your account settings.

I do not have a receipt for Minecraft Java Edition on my Microsoft account because I bought it through the Mojang store before the Microsoft/Mojang account integration that happened a few years ago. Thus, my Microsoft account doesn't have a receipt for it because I didn't buy it through Microsoft. I can give my Minecraft username as evidence that I had a copy of Java Edition but besides that I have no other evidence. Now that my Mojang account has been migrated to Microsoft, I can't log in to it to prove I own a copy of Java Edition.

I got minecrat from Microsoft Store. So the account I bought was already a microsoft account. My account has nothing to do with mojang. I can't send verification code because I didn't get it from Mojang. My account is already microsoft account, why do I need verification but? I'm not a Mojang account

Hello, that’s the problem. I cannot log in my old account through mojang, I’ve asked for help, they said, that it had been migrated and linked to Microsoft account. There’s on my Microsoft account new Mojang account which hasn’t got nickname I played with in mojang and license either

Sorry, I was very unclear with my earlier question.

I have a Mojang account that was transferred into a Microsoft account, but when I started up Minecraft, it wouldn't let me join multiplayer, and I now I can't change my settings or check what family i'm apparently in since I'm in a family for some reason.
