Hello, some days ago I made factory reset of my iPhone 6 64GB (iOS 9.3.1.). After clean install of iOS photos/videos automatically downloaded to my iPhone from iCloud but I have a problem with videos. If I want to open some video it loading very slow. I see ring and after 30-60 seconds video starts to play. Some days ago I was on one place where signal was weak so I can't play videos in my iPhone. Have iCloud Photo Library turned on and have checked option "Optimize Photo Library". If I choose "Download and Keep Originals" will it fix my problem? Thank you so much.
