Mastery Flair problem.

Since yesterday I've been trying to update my mastery flair, as you may imagined because of the title, but I keep receiving this message: "Something went wrong! You listed your in-game name as EchoeWraith. If this is correct, Paladins' servers may be having issues, or there may be an issue with special characters in your username. Please contact u/DrYoshiyahu if you believe this is a mistake."

Anyone else is dealing with the same issue?
