Thank you for the reply - My device is an iPhone 16 Pro, running iOS 26.0 and has developer mode enabled. I have followed all of the steps, including adding the GameCenter capability, and modifying my scheme by enabling debug mode for GameKit Configuration. There is the one line that says "For Mac targets, ensure that you enable both Incoming Connections and Outgoing Connections in the App Sandbox capability under Network." Do I need to do that, even for an iOS target?
