All my photos have synced from my MacBook to my iPhone and I also have it set to optimise the storage. Yet last night and still today the phone says it is UPLOADING over 3000 images!!! How can this be right if the photos aren't even originally on the phone. Nothing I add to the photos app now on Mac will sync across as the phone is uploading 3000 images that are not even on the phone. How do I stop it syncing?!?
