Ok so apparently there’s a restriction that you can’t change your username if you are under 18 which I see as unnecessary and really inconvenient. Every time I want to friend somebody I know, I have to check with them somewhere else that its really them or that its me trying to add them when I could just look at the username and know its them. I understand the intent, restricting kids from changing their user is unnecessary. At least make it so that 13+ users can change their username.
TLDR: only 18+ users can change their username and I see it as unnecessary
