O.P. I can't change my name
(I am French so sorry for the mistakes)
I can't change my profile name, when I change my name, nothing changes, when I write something, my friends see my profile name but I see another name (the name of a friend ).
Yesterday I added an email address, I was asked to put his name and surname, but in the end it was I who had his name, and I can not put my original name
