I have the same question. Even in their own documentation, Apple is still saying that you can use this tool to generate badges and links to your app, but it seems like apps are removed from this site. https://developer.apple.com/app-store/marketing/guidelines/

I think I may have found the solution -- the app has been successfully uploaded and I'm submitting it for review as I type. Solution: In project settings -> main app target, make sure "supported intents" does NOT include your intent which is detailed in your intents extension. For some reason this seems to be leading to the issue. Removing the "supported intent" from the main app did not seem to make a functional difference.

I have a similar situation here, where I rely on the Intents Extension to make my Widget Extension configurable, per Apple's own documentation. I only have 1 Intents Extension and I'm not sure why I keep getting this error... https://developer.apple.com/forums/thread/662007?login=true&page=1#636779022

@Sash unfortunately nothing yet. I'm double-checking everything as I pretty much followed Apple's own guide on how to make this: https://developer.apple.com/documentation/widgetkit/making-a-configurable-widget I'm in touch with Apple Support so maybe they'll get back to me on this.
