I recently bought osu supporter and was wondering how to change name. I click change username on my profile, but it says I have to buy one although it said I get one free name change with buying supporter. Thank you!
If it says you have to pay, try giving it a few hours (or a day or two) to updated, though to my knowledge, should be nearly instant. If it hasn't updated then, please feel free to contact support@ppy.sh
