I asked this question already but I wanted to rephrase it. If I log into my iCloud on someone else’s phone, if I select the “backup” option on settings, will their data merge to my iCloud? I remember at one point I got a pop up saying that data could not be merged because things like messages or photos did not belong to the same iCloud account
When you login to another device with your ID, you will see the notification asking if you wish to merge the data so you won't have to initiate a backup to see that notification.
