Does not trigger with a subdomain on iOS

[wijesijp]

I have following in my apple-app-site-association file

{
    "applinks": {
        "apps": [],
        "details": [
            {
                "appID": "oooo",
                "paths": [ "*" ]
            }
        ]
    }
}

In associated domains I have added it with a subdomain like applinks:dev.abc.com
The application does not seems to get triggered.

However if I add applinks:abc.com as associated domain the application does get trigged.

Is there a way to get it working?

If your site uses multiple subdomains (such as example.com, www.example.com, and support.example.com), each requires its own entry in the Associated Domains Entitlement, and each must serve its own apple-app-site-association file.

You must provide the apple-app-site-association for each subdomain once a time your domain has subdomains and you would like to associate them with your app.
