Default App Clip URL (appclip.apple.com) shows website preview instead of triggering App Clip card

We have a published, approved App Clip that works correctly via QR code and the Safari Smart App Banner, but URL-based invocation does not trigger the App Clip card in any context.

Most notably, Apple's own default App Clip URL does not work either: https://appclip.apple.com/id?p=hazel-torus.Clip

**Tapping this link in Messages or Notes does nothing. **

Long-pressing it shows a generic website link preview rather than the App Clip card, even though appclip.apple.com is Apple's domain and requires no configuration on our end.

Setup details:

App Clip bundle ID: hazel-torus.Clip

Team ID: 2UNR2APH47

App Clip experience URL: https://passportreader.app/open

AASA includes a correctly formatted appclips key with 2UNR2APH47.hazel-torus.Clip (confirmed via https://app-site-association.cdn-apple.com/a/v1/passportreader.app that AASA is correctly cached)

Associated Domains entitlements (appclips:passportreader.app) are present on the App Clip target

App and App Clip experience are both Approved / Ready for Sale

Tested on two physical devices, neither with the full app installed

Since QR and Safari banner invocation work, the App Clip itself and its entitlements appear correctly configured.

The fact that even Apple's own appclip.apple.com URL fails, and is treated as an arbitrary website link, suggests this may be a backend indexing issue specific to this App Clip rather than a client-side configuration problem.

Has anyone else encountered this, or know what could cause appclip.apple.com to not be recognized as an App Clip URL?
