I need to link my SWGOH account to my EA

I tried to link my EA account to the game but after completing the steps, I was met with a message saying that my Birthday in game didn’t match my EA account birthday. I check and my EA birthday is correct, but I can’t change my SWGOH age or even see what it is to match it to my account. 

Idk what I put as my birthday in the game, but it’s obviously wrong and I need to change it if I want to link my account. 

Any advice?
