问题
What I want to do:
Suppose that on FB-enabled game, A invites B. I want to use deferred deep link (on new installation) to trackback B's installation and launch, then give "invite reward" to A. That is, I must find a way to pass context from A's invite and stays until B's installation, which deferred deep link 'should' do the work.
Problem:
App link URL specified when calling FB.Mobile.AppInvite on A's side will not reach B on first app launch, neither as deep link or deferred deep link. FB.Mobile.FetchDeferredAppLinkData does state that
Deferred deep linking is also useful to pass context on a new installation when using FB.Mobile.AppInvite.
But "Test deep link" tool from App Ads Helper tool did work and I got deferred deep link as intended.
These are steps I done
- A only has the app while B is not. A invites B.
- B goes to his FB notification, presses install on invite. At this point, I tried both install from real play store and switch outside then manually install APK by package manager.
- B launches an app, no deep link or deferred deep link provided. (Instead, if Test deep link were used to create invite, deferred deep link will show up here)
Question:
- How to make app link reach B on first installation/launch? Or is there another trick or work around?
- If you are Facebook's developer team, maybe can you confirm that if this AppInvite really goes into deferred deep link or not? Or deferred deep link only designed for ads tracking?
Note:
- This was tested on android.
- I have already setup deeplink option on FB app settings, and it passes check lists on App Ads Helper tool.
- I have already delete the app on B side every time I tested.
- I'm on Unity Facebook SDK 7.6.0.
- I know that there are 3rd party service such as branch.io that might help, haven't tried those yet. I want to see if bare integration with FB SDK will work out of the box or not.

回答1:
Creator of this Facebook Developer bug report here confirmed that it was fixed in his case. So this issue was somewhat from plugin bug itself.
Still not fixed in my case, maybe due to different android activity configuration / presence of another plugins. But I will conclude this as answer to the question then.
