What about my apps not downloading?
I transferred data from my old iphone 8 to a new iPhone 12. The old apps aren't downloading though. Its been two hours and they haven't downloaded. I can't get them to actually begin downloading.
You need to be connected to a stable wi-fi connection and the device should be connected to power to keep wi-fi from going to sleep. If they do not start downloading, force restart the iPhone using the instructions here, Force restart iPhone - Apple Support That should get them to start downloading again. The amount of time it takes is going to depend on how many apps you had on the device.
