I'm having an issue with Photo Shuffle on my iPhone 17 Pro Max with iOS 27.0.
Photo Shuffle has always worked perfectly up to the recent upgrade to iOS 27.0.
It is configured to show photos from my collection both in the background and in the lock screen and to change them "On lock".
After the upgrade to iOS 27.0, from time to time, some of the photos are shown as a uninform green-gray both in the lock screen and in the background.
Starting from the lock screen, when I select the configuration of the background and choose customize, I can cycle between the photos by "tapping to preview" and, once the green-gray one comes out, if I select the "Show photo in library" from the photo menu, it is correctly displayed from the Photos app.
If I remove the specific photo by selecting "Remove" from the photo menu everything goes fine for a while until, usually after a day or two, another green-gray photo appears.
It seems that the problem appears when Photo Shuffle tries to show some photos that were never showed before but am not 100% sure about this.
Any suggestion on how to fix the issue?
In attachment you can see how the background looks like when one of the green-gray photo is selected by Photo Shuffle.
Thanks in advance for any help.
