Describe the bug
I have integrated Firebase as per the RC documentation. Events are getting sent from the RC successfully with the status code 204. But when checked the events on Firebase then they are not appearing there. Its been around 2 weeks but no events are appearing for IOS and Android both.

1. Environment
   1. Platform: Android and IOS
   2. SDK version: 9.6.15
   3. OS version:
   4. Xcode/Android Studio version:
   5. React Native version: 0.73.11
   6. SDK installation (CocoaPods + version or manual):
   7. How widespread is the issue. Percentage of devices affected.
2. Debug logs that reproduce the issue
3. Steps to reproduce, with a description of expected vs. actual behavior
4. Other information (e.g. stacktraces, related issues, suggestions how to fix, links for us to have context, eg. stackoverflow, etc.)

Additional context
Here is one of the payload sent from RC:

{

Hi @helians11, thanks for reporting! A few quick questions for you:

1. Where in Firebase are you looking for the events to appear?
2. Can you verify in your integration configuration in the RevenueCat dashboard that you've used the correct Firebase App ID and API secret?

Thanks!

1. I am checking the events on Firebase events dashboard which is connected with my app
2. I have validated the configs, app id and API secret are correct only.

One pragmatic thing to check while RC support digs in: GA4 event ingestion and the Firebase DebugView / Events dashboard are not the same thing timing-wise. A 204 from the Measurement Protocol endpoint usually just means Google accepted the payload syntax, not that the event will immediately show up in the standard Events screen.\n\nGiven your payload already includes a valid-looking app_instance_id, I would verify this in three layers:\n\n1. DebugView vs standard Events dashboard — if you are testing live and expecting instant visibility in the normal Events tab, that can be misleading because aggregated reports lag.\n2. Correct Firebase property / app stream — make sure the app_id RevenueCat is targeting matches the same Firebase project + app stream you are inspecting for both iOS and Android.\n3. GA4 custom definitions / ecommerce expectations — some params in the raw payload won’t appear as visible dimensions until they are registered or surfaced by GA4 in the way you expect.\n\nThe main distinction is: HTTP 204 != guaranteed visible event in the dashboard you happen to be looking at right away. It mostly tells you the request wasn’t rejected at the edge.\n\nSo if RC has already confirmed the App ID and secret are right, I’d next verify whether the events appear in DebugView / Realtime first, then compare against the standard Events report after delay. That at least separates “RevenueCat never sent something usable” from “Google accepted it but the reporting surface is lagging / different than expected.”

@agenta-works-dev Is there any update ?
