Steps to reproduce

Facebook SDK Version
[v16.0.0]

Device models
[Android 11, Lenovo TB-7306F]

We were implementing Deferred Deeplink with our app.
For this, we went through the following documentation.
https://developers.facebook.com/docs/app-ads/deep-linking/
This way, we completed our implementation.

And for testing we using
https://developers.facebook.com/tools/app-ads-helper/?id=925486975940053
And we followed the following steps for testing.
On the testing webpage, We selected the app, and clicked "Deep Link Tester"
After filling the "deep link" and selecting send notification tick box, we clicked "Send to Android".
Now in the Mobile FB App we got a notification mentioned "Tap to launch your deep link"
Now uninstalled our app then click on the button "Tap to launch your deep link"
It took us to the play store to download our app.
Here we installed our app from Android Studio in Debug mode.
But for each testing, we were getting "appLinkData null"
And if we selects both the ticks than we are getting a popup with a message
"The link has been queued and is pending you doing a first app launch on your device. This means you need to delete the app, then re-install and open your app. Please first verify your app can handle deferred deep linking by checking the iOS and Android setup information located above."
We did a lot of debugging and troubleshoot but did not get any success.

So the result of our findings is as follows.
This Account Facebook App is having some issues.
Its opening the app but the "appLinkData" it giving value null.

                Log.d(TAG, "onDeferredAppLinkDataFetched: AppLinkData: " + appLinkData);
                if (appLinkData != null) {
                } else {
