I singed in with my brothers Microsoft account but he already had a Minecraft account so I loged out of it to put another account for myself but it just doesn't let me sign in on another account and it's so stressing I didn't pay 8€ to not be able to play with my friends, because my brother can enter with another account but I can't it's like a bug that doesn't let me do it, also my brother decided to give me his account, but I can't change the name, it says I need to pay 10€ to do so.
