Update: For those of us happy taking many photos and using iTunes to back them up, don't believe that they are safely stored there - just check that your backup matches the images on your phone and that all are viewable in your backup / restore. You may see the message 'file type not supported' for .jpg, and 'file type not playable for .mov' .
Apple are apparently aware that iPhone XS Max users are having this problem of missing photos / unusable format messages and apparently trying to fix it. If anyone else has seen this would appreciate if you can share your story.
