I have created a TWA Progressive Web App directly by the guide on this google page:
https://developers.google.com/web/updates/2019/02/using-twa
And have added both the asset statements in the app and the assetlinks.json on my two domains exactly as described on google's sites.

When opening the app, there is no displayed app URL bar. However, if I click on a link to go to my second domain, the URL bar appears.

How do I make the URL bar remain hidden while navigating between my two domains?

Here are my assetlinks.json under /.well-known/ on the domains and asset_statements in the app ---
assetlinks.json:


    [{
    "relation": ["delegate_permission/common.handle_all_urls"],
    "target": {
    "namespace": "android_app",
    "package_name": "com.exdomain.exsub.app",
    "sha256_cert_fingerprints": ["59:81:22:DC:B0:16:95:A4:2D:F3:47:16:2A:9D:F6:63:E0:D2:99:DD:36:ED:9C:ED:6B:C6:39:4A:89:E3:E9:24"]
    }
    }]

app asset_statements:


    [{
    "relation": ["delegate_permission/common.handle_all_urls"],
    "target": {
    "namespace": "web",
    "site": "https://first.exsub.exdomain.com"
    }
    },
    {
    "relation": ["delegate_permission/common.handle_all_urls"],
    "target": {
    "namespace": "web",
    "site": "https://second.exsub.exdomain.com"
    }
    }]

You'll need to configure the Trusted Web Activity to be multi-origin. Here's the documentation explaining how to do it: https://developers.google.com/web/android/trusted-web-activity/multi-origin
