Deferred Deeplink issue on this Facebook App previously its was working fine.

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 both tick boxes, 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"

We did a lot of debugging and troubleshoot but did not get any success.

5-6 months back it was working properly.

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.

So please check this Facebook App, why Deferred Deeplink is not working in this Facebook App.
