Resolved ? I have the same problem too but android doesn't work either. For android what have you configured ?

@invyctus92 no special for android.

Still missing reproduction, no activity. Can always reopen, but closing to clean issue list.

Android is working fine for me. In my case the exact same thing happens for iOS.

I have a regular setup in place, as in the docs. The only thing that have in my codebase is the SDK initialization, a method setAdvertiserTrackingEnabled(true) invoked at the startup and AppLinks.fetchDefferedAppLink run on the app mount, lets say.

Having it tested on my iPhone (iOS 14+) I could not fetch the link, it always is nil (no errors though)

In order to try and resolve it, I created my own fork with updated iOS Facebook SDKs (had to remove/replace some methods that are removed). Still NOT WORKING

Then, I turned on my old iPhone with iOS 12.4.6 and went to Settings -> Privacy -> Advertisement -> Reset advertisement identity. Then, when I used the deferred links debugger, I was able to fetch provided deep link.

Unfortunately, having done the aforementioned steps on iOS 12, it still does not work on iOS 14

@danielmark0116 this could be really really valuable as the start of a fix for #55

n order to try and resolve it, I created my own fork with updated iOS Facebook SDKs (had to remove/replace some methods that are removed).

@danielmark0116 How android works for you. Can you please tell us the setup for android? And did you get the iOS to work?
In my case both are not working, ios returns undefined and android returns null.

Im doing this after getting user consent,

Settings.setAdvertiserTrackingEnabled(true).then(() => { Settings.initializeSDK(); AppLink.fetchDeferredAppLink().then((link) => console.log('Link ', link)); //undefined in iOS and null in android });

Please check this #234
