I was in the middle of transferring my information from my old Iphone 7 plus, to my new iPhone 12, and I got the message "no backups available." I can choose to "set up as a new iPhone" or "restore from mac or PC. I don't know what data there is no back up of. Did some of it transfer?
iPhone 12, iOS 14
Is there a backup of your iPhone 7 that can be downloaded on the iPhone 12?
