I did a full reset of my phone after doing an iCloud backup (and have all my photos naturally uploaded to iCloud). Since then, none of my images have shown up in my photos app. Steps i've taken - Did a second reset - Went into iCloud > Photos > Turned off iCloud Photo Library, Turned in Back on. Notes - When looking in the iCloud breakup, it shows my photos. - I logged into iCloud.com and my photos are there. Has apple changed it so rather then progressively downloading images, it waits and does one big download? --- Post Merged, Sep 25, 2017 --- Two seconds after posting this my images have started to download.. So i guess you can consider that fixed. Hopefully if anybody else has issues, perhaps the information above may in some small way help.
