DJI Go 4 - LIVE broadcast can't change Facebook account?

Have been playing around with LIVE broadcast using Facebook as platform. But for some reason I am unable to change the Facebook account on iPad Mini. App keeps defaulting to wifes Facebook account. I have deleted Facebook and reinstalled and have even defaulted the iPads Facebook login details in settings to my name, but somehow it keeps wanting to use wifes Facebook account to stream. Where is Go 4 app pulling Facebook login details from? Why cant I change it?

When I sign out then login again the app somehow defaults back to wifes Facebook account without any option to select another account.
