[READ] Step 1: Are you in the right place?
I believe I am :)
[REQUIRED] Step 2: Describe your environment
- Xcode version: 11.1
- Firebase SDK version: 6.12.0
- Firebase Component: Analytics, Core, InAppMessagingDisplay, GoogleTagManager (7.1.2)
- Component version: FirebaseInAppMessaging (0.15.5)
[REQUIRED] Step 3: Describe the problem
InAppMessagingDisplay stops displaying messages triggered by analytics event when Google Tag Manager is used, more correctly when container JSON file is added to project.
From what I debugged, method messageTriggered:parameters: on FIRIAMDisplayCheckOnAnalyticEventsFlow is not invoked on analytics events when mentioned JSON file is included. Not sure what could be the issue but maybe GTM internally swizzle something or doesn't call super implementation, since if I remove JSON container from project that method is invoked and messages are shown.
Steps to reproduce:
I've created example iOS project where you can reproduce the issue: https://github.com/fgulan/fiam-gtm-issue. Google plist and GTM container json are included in project with my test data. Just run the app and you should see the button which triggers analytics event open_fiam which should trigger displaying FIAM banner message with text Test FIAM. But it doesn't since JSON container is added as a reference, just remove it to see the difference.
