Account connected via Ipad to Droid (with FB) Got new Iphone can't port over

IIIPA

Not using game center ( as my son logged in and used game center for his account ) I have my main account on an IPAD connected to facebook. Anytime I try game center it ports in my son's account. I downloaded SWGOH onto the new iphone and there is no option to link facebook. I just wanted an option to be able to use SWGOH on the phone when out and about. Has anyone had a similar issue. EA support wasn't able to help as it wasn't a transfer issue between Android and IOS ( Already had this done for me when I got my last droid before the iphone).
It seems that there should be a link device option available but there isn't (not when starting fresh, or logging into game center under that other account)

Any thoughts?
