"No Domain URL Status data" for my App Clip Associated Domain on App Store

Hello Everyone, I'm trying to view status for my app clip associated domain from the Build MetaData in TestFlight tab, but it keeps giving me "No Domain URL Status data".

Also, when I'm trying to create advanced experience by adding my invocation domain (https://appclip.example.com) to the App Clip Experience URL, I'm getting "This URL is not contained in your app’s associated domains. Update associated domains or use a different URL."

Here's my configurations:

• Associated Domain in both App Clip Target & Main App Target is (appclips:appclip.example.com).
• The AASA file is added with no redirects on (https://fully-qualified-domain/apple-app-site-association) & Content-Type is application/json.

{
    "applinks": {
        "apps": [],
        "details": [
            {
                "appID": "1234567890.com.example.appName",
                "paths": ["/*"]
            }]
    },
    "appclips": {
        "apps": [
            "1234567890.com.example.appName.Clip"
        ]
    }
}

My Questions

1. What's missed for not obtaining Domain URL Status data when tapping view status?
2. Why I'm getting "This URL is not contained in your app’s associated domains" when I'm trying to create advanced experience although this domain is already in Associated Domains ?
3. The invocation url (https://appclip.example.com) is redirecting to (https://example.com) on the website. Does that may cause an issue ?

Please note that I have included (appclips:example.com) also in the Associated Domains & tried to create advanced experience using (https://example.com) but I got the same issues.

Thanks in advance!
