Dynamic links in Facebook mobile app is not deep linked to app - firebase

Question

Problem — when opening a Firebase Dynamic Link on Facebook Mobile, the Facebook Browser consumes the deep link and does not open the intended mobile app
Question — is there a good workaround in Firebase to help Facebook deliver on the promise of presenting my Dynamic Link as intended?
We are aware of http://applinks.org, and that Facebook is a contributor. Does Firebase have a way to configure their server using the AppLinks spec so that Facebook will pass through the Deep Link to our app instead of consuming it?
Background — I have created a Firebase Dynamic Link for an iOS and Android app.
The Dynamic link delivers everything I expect and is a fantastic experience.
When opened on iOS, it navigates to the App. If not installed, it goes
App Store
When opened on Android, it navigates to the App. If not installed, goes to Play Store
When opened on non-mobile, it navigates to our Website
On Facebook mobile, neither 1 nor 2 happens. The result is that it goes straight to the mobile web experience, thereby eliminating the promise of the Firebase Dynamic Link

Answer 1

To avoid this cases we made a webpage which redirects to firebase dynamic link.
With this solution we can:
Use our domain, not the firebase url.
Ensure that firebase links works in every cases, for example when it opens from a custom browser (fb, samsung).
The disadvantage of doing this is that you'll always need to pass through a web page with an redirect.

I recently had to integrate dynamic links to one of my clients apps, and I got lots of trouble because of deeplinks not working on facebook+android_app.
As I couldn't move to branch.io because of princing reasons, I had to work it out on a different way so followed #Rahul Shukla advise.
I ended with a very simple nodejs+express setup where I receive the dynamic link ID and return a HTML with all the meta-tags required by facebook applinks (android + iOS) and a redirect script (window.location = 'your_dynamic_link') for other clients to be used.
The best part is that now on facebook the app opens directly without the preview page in both platforms and the link works on all browsers via the script redirect.
Here is the gist

Answer 3

the solution I found was to redirect to the dynamic link from a webpage like this
window.location.href = "intent:https://example.page.link/2wertygf456#Intent;end";
this will open the link in your system default external browser and the deeplinks works perfectly.
to trigger this only on facebook in-app browser
if (ua.indexOf("FBAN") != -1 || ua.indexOf("FBAV") != -1) {window.location.href = "intent:https://example.page.link/2wertygf456#Intent;end";}

We were struggling with the similar issue and here's how we finally solved it:
Say this is the final firebase url you are going to share
https://xxxx.app.goo.gl/?apn=com.your.package&link=http://www.yourwebsite.com
Now in the index.html page of your website, add the following meta tags
<meta property="fb:app_id" content="your_fb_app_id" />
<meta property="al:android:package" content="com.your.package" />
<meta property="al:android:app_name" content="YourAwesomeApp" />
<meta property="al:android:url" content="somescheme://XYZ" /> <!-- identifiable by your app, your app must handle this data scheme inside your manifest's intent-filter tag --!>
<meta property="al:web:should_fallback" content="true" />
<meta property="al:web:url" content="http://www.yourwebsite.com/" />
Now the app launches on clicking on the facebook post shared using this link.

I've tried some ways but totally fail. When I use the dynamic link in Facebook post, it shows a dialog to ask me if I wanna open application (I did not install my application yet). Although I accept to open app, nothing happens, it does not open Apple Store as expected
I have to use link like below to force it open apple store app
https://myapp.app.goo.gl/?link=http://mylink.com&ifl=https://itunes.apple.com/us/app/apple-store/idxxxxxxxx%3Fmt%3D8%26ct%3Dutm_source

Deep link with facebook app not work in android because facebook uses InAppBrowser, If you want to make your deep link url workable in facebook. You can change facebook settings like:
In Facebook App: Goto Profile -> App Setting -> check Links open externally.
After changing the setting you will be open deeplinks from facebook app android
