I just bought a new iPhone 11 pro max.
After turning it on and did some very simple settings, it asks me to transfer data from my previous iPhone.
However, I accidentally switched to another app on the previous iPhone. After switching back to the home screen, the popup about transferring data was gone. I could never manage to restart the "Quick Start" feature.
How can I restart the "Quick Start" feature so that I can complete transferring apps from the old phone to my new phone?
