I tried on my browser than in the windows client but received this same error and do not understand why, after looking at a different post I saw the error for being linked to the wrong discord has a different error message than this, so i am making this ticket. I assume that maybe its because when I go to link it, the discord that it shows my account having my username with an addition #0 at the end.
Thank you for any assistance.
Look like you did t change your discord name when was this discord name migration? Try to change your discord name and disable that "Legacy Username" from your discord settings.
Settings - Authorised Apps -Electronic Arts
If you have it authorise then deauthorise and try again.
my discord username is their current format. I dont know why its adding the additional #0, since I dont have a discrim tag.
I did the reauthorization process you said and tried to link my account, but received the same error again.
Maybe that post helps?
