Hello, Mojang team.
So I recently wanted to change my username in game (IGN) and this message pops up

Oh no! You can only change your name every 30 days.

Your last name change was on 4/16/2021. You can change it again in 0 days.

And I don't really know why it's 0 days.
I waited for 8 hours and nothing
It may be a bug?
