Trying to turn on iCloud photos with concerning pop-up
I recently upgraded my iCloud storage to sync my photos across devices. I have an old iPhone 7 that I want to share photos from, but when I tried to toggle "iCloud Photos" to "on", I received a pop-up that says the following:
iCloud Photos Will Be Deleted Soon
Photos and videos will no longer upload unless you cancel this deletion in iCloud Storage Management.
I then have the option to Enable, Manage iCloud Storage, or Cancel. My iCloud storage management lists Photo sharing as "on" (as it is active on other devices without issue). Can anyone please explain if this is safe to Enable? I don't want my photos deleted and manually copying stuff would be a pain.
See below for my iCloud Storage management settings summary.
iPhone 7, iOS 15
