Hello, im new to the forums, but i need help. i keep trying to change my display name, but everytime i try, it tells me "Sorry, we could not set your display name, please try again later" and its been doing this for three days now. i have followed all the right steps to change it. profile- edit display name and i get the right box for it, but it wont let me. the grid status says that all systems are operational, so i cant figure out why it wont let me change my name. i didnt find any other troubleshooting pages for this, so i thought i would try my luck here.
