photos aren't uploading from iPhone to iCloud Photos
Neither the Photo app on my iMac nor the Photos in iCloud are up-to-date with pictures I've taken on my iPhone (however, the Photo's on my Mac and the Photos in iCloud are synced.) The last photo on Photos is dated 9/5; I've taken many pictures since then but they've not uploaded from my iPhone 6+. I've checked the "settings" on all devices and for iCloud and they all indicate photos would be uploaded to iCloud. I have IOS 9 on my iPhone 6+ and El Cap OS X on my mac; Photo's version 1.1 on my Mac.
It appears there's an update available for iPhoto version 9.6.1 but when I try to update it I get "An error occurred during purchase" message and when I click on the icon for iPhoto in my App updates screen I get a message saying that product isn't available in the U.S. store.
