Unable to Add Guest Order to Apple ID
I've been having trouble adding an order I had to place as a Guest to my Apple ID. I always receive an error that says, "Something went wrong. Please try again later." - see attached screenshot.
I've been trying this for WEEKS now and it still doesn't seem to be working. I've even tried different browsers, clearing my browser history and cache... no resolution. I even tried calling Apple Customer Service and they said they can't help with this issue over the phone. Anyone else have luck with this?
