My photos won't upload to my iCloud Photo library
My iPhone has been trying to upload 1141 pictures to my iCloud Photo library and it has been stuck there for 2 days. I've been away from any Wi-Fi connection for the last week and before I was gone, my photos would upload without any problem. Now that I'm back and that I have a fast Wi-Fi connection available, they won't upload. What should I do?
iPhone 6, iOS 8.4, 16GB
