Some Apps’ data and passwords don’t get transferred when you change iPhones.
Google Authenticator and Signal are among two that I found needed QR codes to transfer directly between the phones.
What are some Apps you needed to manually transfer?
Has anyone made a list or found a Wiki that would be helpful to people changing phones?
I’m not sure I understand what good it does to see a QR code on your screen (vs. pointing camera at code that takes you to the sale site). How do you use a code from your phone when you don’t have anything to scan?
