My son and I have been taking turns on the same Minecraft account for awhile now, but I want us to be able to play together, so I created a realm, and I'm trying to create a second account, but I receive the following error message: "You already own one copy of Minecraft on this account."
I think the problem is that although he has his own email address, he is a minor, so they require the parent email address, too.
Anyway, super frustrated. It's never taken me ALL AFTERNOON to buy a video game before!
