Passwords not transferring from iPhone 12 Pro Max to 15 Pro Max
Purchased an iPhone 15 Pro Max to replace my iPhone 12 Pro Max.
when setting up it asks if you want to transfer from the old phone but then it asks which back up you want to use. The process of updating from a back up seems to be taking ages. It looks like the password aren’t transferring to the new phone. Do I have to wait until the update from the iCloud is complete? Key chain is switched on.
iPhone 12 Pro Max, iOS 17
