Posix error
I bought new phone so I wanted to transfer my photos to that phone. All of my photos are saved on iCloud, but I can't download them on my iPhone. The problem that I have is that when I downloaded photos from iCloud, I got a zip file that i couldn't open, and this is what it says: The operation couldn't be completed - POSIX error -1 ; Unknown error -1). What should I do?
iPhone 12 Pro Max, iOS 14
