icloud photo storage from iphone
A few days ago, I opted to automatically upload and store photos in icloud (with the choice of optimising iphone storage). I then decided I preferred to just download all my photos onto a USB from my iphone (via my mac). When I went to do this, many of my photos were missing from my library (as they are now being stored on my icloud.
I then went back to my settings on my phone and un-clicked the option of automatically upload/store photos in icloud with the intention of then re-downloading all my original photos and videos onto my phone. I then get a message saying "Cannot download photos and videos - An additional 10.4GB is required to download your photos and videos to this iPhone. You can manage your storage in settings"
I do not understand how a few days ago my phone had enough storage to hold all my videos/photos and now I need an extra 10.4GB to re-download them??
PLease help, i really dont want to lose my photos
iPhone 6s, iOS 12
