Photo Stream not showing all photos
I have 795 pictures on my camera roll, but my photo stream only shows 105 (the most recent ones, I'd say they go from today to two-three weeks ago). Up until yesterday it showed all pictures. My photo stream had more pictures than the camera roll, they were about 810 I think. I haven't done any changes to the settings, no backups, nothing. I recently bought a new laptop and I have installed iCloud on it, only set it up with email and Apple ID, haven't connected my phone to the laptop yet.. long story short I haven't done anything weird to justify all those pictures not showing up as they did. Never had this issue before.. iPhone 4 running iOS 7.1.02
iPhone 4, iOS 6.1.3
