I implemented rich notifications on iOS 10, using built-in template with image as attachment, visible on banner and on long view. Everything was working fine.
Now on iOS 11, I find that the image doesn't show if the notification appears on the home screen, and the user goes into the long view.
However, if by chance the notification appears at least once on top of the app UI, the image shows just fine.
From that point on, the image will consistently show, even on the home screen.
Note that my code hasn't changed, except for updating to Swift 4.
Is this a known issue? Should I file a bug for this?
Thank you for any information...and maybe there is a workaround?
