Friends of mine have an iPhone, I think it's a 6, running ios 10.3.3 and they are on AT&T. Every time I send them a picture using Messages, they don't get the picture just a box saying touch to download the picture. When tapping the box the pictures do download and show up. This is the first i have heard of this issue. Anybody know what I can check or change to allow their phone to download the pictures automatically?????
