Unil the past week or so Photo Stream would update my photos on my iPhone, MacBook Pro and iPad practically within minutes. I've noticed the past fw days though it is taking forever to update. Earlier today I took about 35 photos, and as of now, a good 8 hours later only about 10 of those photos are showing in my photo stream. I took them with my iPhone 5 and they appear in the Camera Roll, but nowhere in Photo Photo Stream yet.
