So I just recently got an iPhone 8 64GB on iOS 11.0.3.

I'm having a problem where in an app, if I hit save photo (in whatever fashion they provide the button) sometimes it will not save to the photos app. I never had this issue on my iPhone SE on iOS 10.2.

Another thing is in 2 of the AR apps (PaintSpaceAR and LightSpace) whenever I try to record in the apps, both of them will fail to save. Lightspace even throws an error saying that the screen recording failed. I have tried out screen recording by itself and the camera app and both save to photos perfectly, so it's just when 3rd party apps try to use these features.

I was thinking maybe it's just those apps so I tried other ones and the same is true. Has anyone else had this issue before and have you solved it?

I have tried uninstalling/reinstalling apps and even did a full backup/restore of my iPhone and neither worked. Thanks for any help!
