When I am talking to my friends via imessage, I dont get any of the messages for about 5 minutes, then they will all come in at once. Sometimes when using group chat, i'll get about 20 messages at once. I have tried doing a hard reset, closing the imessage app all the way, turning the phone off and back on. I don't know what's causing this issue, or how to fix it. Do any of you know, or maybe have the same issue?
