Im really frustrated with this thing because i buy the game for play with my old hotmail microsoft account, and a create a few years ago a minecraft.net account, than i migrate that account to microsoft, no problem with that, when first time i play minecraft it was on Gamepass, i create a provisional Username "ravennlegend" and i play normaly 2 months, right now, i try to launch the game after buying, and say that " i need a username" i went to minecraft.net and some bugs i see, the page say that i need to buy the game, but refreshing and another ocasion say that i have the game and can change the aspect and nickname, i set a nickname and today i try to play and i can't, because "i need a nickname" and i have already a nickname ;, wtfreak man. Why is not sinchronyzed  the microsoft account with the minecraft.net man? i have trouble with this thing because that BUG ;; and i cant geet a money refund for create a new account and this thing dont happen to me again but i cant ;-; Refund on minecraft is annoying. im really frustated that i cant play with this thing, please resolve i buy the game with all of my ilusion after playing for 12 years, and is not just that this thing happen.
