Hey, we have multiple image editing apps, and some of our users report a strange behavior where the images exported with our apps vanish after syncing with iCloud.
In more detail:
- The user loads an image from his library
- Edits it with our app(s) and saves it back to his library
- The image appears in his library
- iCloud sync starts, and right after it finished, the image vanishes from the user's library
We narrowed it down to a problem with an older macOS. One of our users has a MacBook with High Sierra 10.13.6, and if he shuts it down, the image remains in his library.
We suspect that our exports are classified as duplicates of the original image, but we are unsure if this is the reason.
Currently, we copy all the image metadata along and only change the modification date.
Any idea why this could happen and how we can prevent this?
