Restore button not responding when setting up iPhone 16

Hi everyone,

I’m trying to restore a brand-new iPhone 16 by transferring the contents from my old iPhone 12, but the Restore button in the Apple Devices app isn’t working. I've already ensured both phones are connected to the same Wi-Fi network and signed in with my Apple ID.

Does anyone know how to fix this issue or have alternative solutions for restoring my data? Thanks in advance for your help!
