My son has iPhone 6+, I have 5s, both on 8.0.2. We already follow each other permanently on Find My Friends. Whenever I send him an iMessage, I get a Find My Friends notification that he is requesting to follow my location. I understand that iOS 8 allows you to share your location with the person you are exchanging iMessages with. How do I get the repeated request to go away? I have allowed it two or three times, but it still pops up whenever I start a new message stream with him.
