one way sunc possible?
How can I continue to sync photos from my phone to iCloud without getting all old photos stored in iCloud to my phone? I just want them in iCloud.
iPhone SE, iOS 14
Sorry, that's not possible.
However, you could transfer the old photos to your computer and delete them in iCloud after that.
