Well, I believe I fixed it.
This took way too long! On the positive side, this isn't Sea of Thieves fault! Simply Microsoft's. I can't believe how complicated this had to be. Simply, my account was registed as a child account (It doesn't really display that anywhere, but on most pages, it says something about children for some reason). So i had to create an alternative account, make that account as "parent". When I then logged in on that alt account, it said that my main also was a parent all of the sudden... -.-
So basically, i had to have a "parent" to become a parent myself? I still don't get it, but that's how I made it work. I couldn't find anything else on this, so hopefully, this might help somebody in the future! It was to be honest, a little bit a pain in the a*s, especially the fact that I'm not a child haha, even my registered birthday was saying i was 21 (Im 18, but it was still registered that).
Deffently confusing!
Good luck everybody experiencing this in the future haha!
- I'm really hype, because I play this solo like 60% of the time, so it has really annoyed me not being able to communicate with people.
