🔥 Dynamic link first open attribution not working on IOS

[harrydema]

Issue

First of all i am not facing issues when i click over a link, my app is opened properly.

I am trying to attribute a campaign, source and medium to a dynamic link install on IOS.

I first open the dynamic link and click over the "open" button on the preview.page.link of the dynamic link. The link is copied to the clipboard.

Then I install the app via XCode and i checked that the dynamic link is fired on the javascript side. The ios function that was fired was application:openURL:options and as i debugged it this was the url:

com.example.app://google/link/?deep_link_id=https%3A%2F%2Fhola%2Ecom%2Ftest&match_type=unique&match_message=Link%20is%20uniquely%20matched%20for%20this%20device%2E

If i click on a dynamic link, and my app is already installed the attribution works properly. The IOS function fired is application:continueUserActivity:restorationHandler

If I check on firebase the event has lots of (direct), which means the attribution failed:

same here, First times install app, it redirect to safari with a message Dynamic Link not found

[harrydema]

Thats not the problem i am facing.
My dynamic link works fine, but the attribution on firebase analytics is the thing that is not working properly.
When ever a IOS user executes a dynamic link, the attribution is tracked as (direct), although the link has utm_source, utm_campaign and utm_medium

[damienix]

I have a very similar problem. I've followed the instructions to setup dynamic links and try to get the attribution working. dynamic_link_app_open event contains campaign info but dynamic_link_first_open does not :( I see the same results on the production version of the app as well as in debug mode while testing. It's working properly on Android. The links are redirecting as expected. I guess there must be something special about handling the initial link that makes it not passing the campaign data.

Is there actually anyone here that has set this up successfully? It would be great to know if there's something wrong/specific with our code or maybe it just doesn't work for some reason. I've also got a confirmation from Firebase team that (at least in vanilla Firebase libs) attribution on iOS should be working too, even on an unpublished app.

It would be great if anyone from Invertase team shared their thoughts on this problem. CC: @Salakar @Ehesp @chrisbianca

Thanks for the help in advance.

I debugged it and found that apparently there's an issue in native iOS Firebase library. I've filed an issue to Firebase team and they just started working on it. Fingers crossed!

firebase/firebase-ios-sdk#2462

[harrydema]

@damienix Thank you for the relpy and the creation of the issue on the firebase ios sdk.
I will follow that issue, but could you pleae keep this ticket up to date so everybody knows when it is fixed? Thanks!

[damienix]

I'll try my best not to forget about that :)

[damienix]

The fix firebase/firebase-ios-sdk#2478 has been merged to master, we're waiting for the release to test: ✊

[harrydema]

Maybe while we wait for the 5.19.0 we can use this:

[damienix]

I didn't manage to validate the correctness of the fix provided by Google. It seems to me that it still doesn't work but that would require further investigation from me which I gave up on.

It's almost certain though the issue is with Google native library and not RNF, hence this issue may be closed.
