so I’ve had this issue in iOS 11 beta 3 and beta 4 . When I send a non iPhone user a photo it shows fine , they receive it and everything but when I come back to it later it just shows a “downloading” image that says it’s already downloaded but never goes away . Singing out of Apple ID only temporarily fixed the issue . I’ve also restored the phone and done everything I know to do . The only thing that fixed this issue with me is downgrading to iOS 10 . I decided to go back to iOS 11 and see if the problem still exists . It does . It’s not a big issue because the contacts still get the photos but it’s just annoying . I know iOS 11 is beta and things are known to go wrong but from what I’ve seen I seem to be the only person with this issue
