Issue with Live CallerID URL Caching

I've been testing the Live CallerID feature using the Apple-provided local server example - live-caller-id-lookup-example. I've been running a local server with tunneling using ngrok for the initial setup. Everything was working perfectly with the following setup:

@main
final class CallerID: LiveCallerIDLookupProtocol {
    var context: LiveCallerIDLookupExtensionContext {
        LiveCallerIDLookupExtensionContext(
            serviceURL: URL(string: "https://example-tunnel.ngrok.io")!,
            tokenIssuerURL: URL(string: "https://example-tunnel.ngrok.io")!,
            userTierToken: Data(base64Encoded: "BBBB")!
        )
    }
}

However, after I updated the URLs to the production ones, I encountered an issue:

@main
struct CallerID: LiveCallerIDLookupProtocol {
  var context: LiveCallerIDLookupExtensionContext {
    LiveCallerIDLookupExtensionContext(
      serviceURL: URL(string: "https://example.net/")!,
      tokenIssuerURL: URL(string: "https://example/issue")!,
      userTierToken: Data(base64Encoded: "BBBB")!
    )
  }
}

The problem is that during calls or when updating PIR parameters, the application still attempts to connect to the initial ngrok tunnel URLs instead of using the new production URLs. I can confirm this because the logs on my local server show incoming requests, indicating that the application is still referencing the old ngrok tunnel URLs.

Steps I’ve taken to resolve the issue include:

• Deleting and reinstalling the application.
• Using reset(forExtensionWithIdentifier:)

Unfortunately, these attempts have not been successful. I even extracted the binary of the app and extension to inspect the strings, confirming that the correct production URLs are present.

The server was started with the following command:

PIRService --hostname 127.0.0.1 service-config.json

Could this be some sort of caching bug on the iOS side, or am I missing something?
