iphone se cannot connect to icloud
We got my son an iphone se last week. We transferred his info from his ipod touch to his new iphone se. None of his music transferred which was fine. We could have him use the music from my icloud account. When we went into his settings, and then Apple ID and clicked on name, phone numbers, etc. and his passwords & security, a message popped up saying "cannot connect to icloud". Everything else works on the phone - texts, emails, phone calls, internet. The phone is connected to wifi. This is the only issue we are having. Does anyone know how to fix this?
