I am having an issue with linking QR code URL to my android app as deep link

Question

Not able to get QR code link to open my app, it always loads in browser.

I have added a intent filter in Manifest file as below -

When I have the link in as SMS message, https://pages.smart.link/abc and I click on that, it shows disambiguous dialog with my app as one of the options to open it.

<intent-filter>
            <action android:name="android.intent.action.VIEW" />
            <category android:name="android.intent.category.DEFAULT" />
            <category android:name="android.intent.category.BROWSABLE" />
            <data
                android:host="pages.smart.link"
                android:pathPrefix="/abc"
                android:scheme="https" />
        </intent-filter>

But if generate this link through QR code, it loads the URL in web browser - tested on Samsung Galaxy S8+

SMS option does NOT work if I have host as "myapp" with final url as myapp://pages.smart.link/abc myapp host works fine if launch it through command line as below -

adb shell am start -W -a android.intent.action.VIEW -d "myapp://pages.smart.link/abc" com.abc.myapp

<intent-filter>
            <action android:name="android.intent.action.VIEW" />
            <category android:name="android.intent.category.DEFAULT" />
            <category android:name="android.intent.category.BROWSABLE" />
            <data
                android:host="pages.smart.link"
                android:pathPrefix="/abc"
                android:scheme="myapp" />
        </intent-filter>
