INPlayMediaIntentHandling, Unable to Trigger App to Play Specific Podcast

I have an app that's capable of playing podcasts via Siri requests, e.g. "Hey Siri, play [Podcast Name]". I’m using INPlayMediaIntentHandling, that is, the SiriKit domain intents, as opposed to the newer AppIntents framework for its ability to select my app for audio playback without the need to specify the name of the app in the user's request to Siri.

This works great overall for the many podcasts I’ve tested the app with, with the exception of one. There's a podcast called "The Headlines", and I when I test the app with the request "Hey Siri, play The Headlines", my app is never selected. Instead, Apple Podcasts begins playback of a show called "NPR News Now".

Oddly, if the Apple Podcasts app is deleted, my app will still not be selected by the system, and instead, Siri responds with "I don’t see an app for that. You’ll need to download one" with a button to open the App Store. Additionally, if I do add the app name to the request using this style of intent, Siri responds with "[App Name] hasn’t added support for that with Siri." However, I’d still like to accomplish this without requiring the app name in the Siri request.

There's nothing complex in my setup:

• The target declares one supported intent, INPlayMediaIntent, with "Podcasts" selected as a supported media category.
• The Siri entitlement is enabled.
• My INSiriAuthorizationStatus is .authorized.
• My intent handler is specified in my AppDelegate as follows:

func application(_ application: UIApplication, 
                 handlerFor intent: INIntent) -> Any? {
    return IntentHandler.shared
}

• My intent handler is simple:

final class IntentHandler: NSObject, INPlayMediaIntentHandling {
    static let shared = IntentHandler()
    func handle(intent: INPlayMediaIntent) async -> INPlayMediaIntentResponse {
    print("IntentHandler: processing intent: \(intent)")
    /** code to start playback based on information found in `intent` **/    
}

• When requesting Siri to "Play The Headlines", my handler code is not called at all. For all other supported shows, the print statement executes, and playback begins as expected.

Is there any way I can get my app to be selected instead of Apple Podcasts for this request?
