iPhone storage is full but iPhone won't upload photos to iCloud
My iphone storage is full. It suggests I upload my photos to icloud to
free up space. I click "enable" and it warns that it will take time, perhaps even overnight. I say "enable" again and nothing happens.
I have plenty of room in icloud. My phone is plugged in and connected to wi-fi. Icloud has only 33 photos -- the ones taken this year and nothing before.
Any thoughts on how to move the photos to icloud to free up space?
iPhone SE, iOS 15
