Android trusted-web-activity (TWA) not hiding url (Digital asset link verification failing), possible conflict with app link setup?

[iamongit]

I have my app set up for use with app links and that part works as expected, I use a link to launch the app and also pass some parameters to my starting page. However I have been trying to add a TWA to open a web page without url bar and I keep getting "Digital asset links verification failed on https://......". I have the correct sha-256 in the assetlinks.json, app link would not work if that was the case. Here's my AndroidManifest and strings.xml:

<meta-data
        android:name="asset_statements"
        android:resource="@string/asset_statements"/>

<meta-data
        android:name="asset_statements_twa"
        android:resource="@string/asset_statements_twa"/>

<activity
    android:name=".MainActivity"
    android:launchMode="singleTask"
    android:theme="@style/LaunchTheme"
    android:hardwareAccelerated="true"
    android:windowSoftInputMode="adjustResize"
    android:exported="true">
    
    <meta-data
        android:name="io.flutter.embedding.android.NormalTheme"
        android:resource="@style/NormalTheme"
        />

    <intent-filter>
        <action android:name="android.intent.action.MAIN"/>
        <category android:name="android.intent.category.LAUNCHER"/>
    </intent-filter>

    <intent-filter android:autoVerify="true">
        <action android:name="android.intent.action.VIEW" />
        <category android:name="android.intent.category.DEFAULT" />
        <category android:name="android.intent.category.BROWSABLE" />
        <data
            android:scheme="https"
            android:host="assetlinkhost.domain.com" /> // My assetlinks.json is hosted here
    </intent-filter>
</activity>

<activity
    android:name="com.google.androidbrowserhelper.trusted.LauncherActivity"
    android:label="TWA"
    android:exported="true">

    <meta-data
        android:name="android.support.customtabs.trusted.DEFAULT_URL"
        android:value="https://assetlinkhost.domain.com" /> // Same domain where TWA html file is hosted under a subfolder, it's a container on Amazon s3 serving static files.

                
    <intent-filter
        android:autoVerify="true">
        <action android:name="android.intent.action.VIEW"/>
        <category android:name="android.intent.category.DEFAULT" />
        <category android:name="android.intent.category.BROWSABLE"/>

        <!-- <data
            android:scheme="https"
            android:host="assetlinkhost.domain.com"/> --> // TWA hosted at the same domain where assetlinks.json is hosted. Commented this out to stop app links from breaking.
    </intent-filter>
</activity>

strings.xml:

<resources>
  <string name="asset_statements" translatable="false">[
  {"include": "https://assetlinkhost.domain.com/.well-known/assetlinks.json"}]</string>

  <string name="asset_statements_twa">
      [{
          \"relation\": [\"delegate_permission/common.handle_all_urls\"],
          \"target\": {
              \"namespace\": \"web\",
              \"site\": \"https://assetlinkhost.domain.com\"}
      }]
  </string>
</resources>

Is there something in my manifest or resources string missing? Asset links file is set up correctly as app links work. The html file I am trying to open as a TWA is hosted at the same domain where the asset links is present. At this point I've also tried to get it to work without any changes related to app links but the verification still fails. Not sure what is missing.

The assetlinks.json should be present inside a .well-known directory which is present in root. Please dont keep the assetlinks direclty into the root
