I have a small bit of a problem. My girlfriends Apple ID is currently linked to her school issue iPad and her personal iPhone. After awhile of iMessaging back and forth on the iPad, my iMessages will no longer go through on her phone and never give the delivered tag. However, I can message everyone else and even receive her iMessages; the only thing I cannot do it reply to her iMessages.
She does not have access to the iPad anymore as she has graduated and had to turn it in.
Anything will help! Thanks!
