Photo stream shows jpg icon instead of image preview
Photo stream shows jpg icon not image preview
My Photo Stream on my iPad (iOS 9.3.5) is now only showing a 'jpg' icon instead of the image preview for any photos taken with my iPhone 7 (iOS 11.1.1).
This is a new problem since upgrading the phone ios. I am at a loss to ascertain what would have changed and my 'googling' only seemed to discuss the concept of photo stream.
any help/ideas appreciated.
iPad mini Wi-Fi, iOS 9.3.5
