As a FB team responses on https://developers.facebook.com/bugs/393947180805373:

Explanation:

5. deleted my app on device 1 ( same device that i used in 1st test. )
6. Clicked the button again the ad.
7. Begin redirected to Google Play.
8. installed my app on device 1.
9. launched my app first time. >> result : I could not see applinkdata, i got null value. ( wonder why ? )

FB Team:

The behavior on device 1 is expected behavior. The app fetches the applink data from the server. When the server gets the request, it marks the ad-applink data as having been fetched. Subsequent requests do not return it. (Otherwise, every time you opened the app thereafter, it would load the applink, which would be a bad experience. The link should only be followed once.). Only if you create a new ad and click on it will the data get fetched again.

I hope it will help.
