Analytics and Adsmanager shows wrong revenue by 2-10x+ for both iOS/Android

[Kendja]

Hi.

I use default conversion events.
Facebook analytics shows me crazy revenue numbers for Android and iOS by 2-10x and more

I also run facebook ads to acquire users for app actions. And revenue for Android shows me 2x than it is.
For iOS everything is correct here.

I use Firebase in the game. Could there be a conflict of some sort that it sends same default event multiple times on Android?

Tested first on April 2019:
Facebook-sdk-for-unity: 7.15.1
Unity version: 2018.3.3f1

Still experience in December 2019:
Facebook-sdk-for-unity: 7.18.0
Unity version: 2019.2.11f1

@Kendja , thanks for your report. Can you report the bug in https://developers.facebook.com/support/bugs/?

[tayl0r]

I'm seeing a similar thing thing, the Purchase event (and all the events are duplicated by 5-6x every time). I would assume this is the reason for the significantly higher revenue numbers.

This is not a new bug. I tested with both the latest SDK, 7.15.1, and our old version, 7.13.0. Both had the same problem. I also reported the bug via FB Developers site.

I'm on Unity 2017.4 LTS

@KylinChang oops, missed your reply.
I sent a bug report via facebook

[Kendja]

@KylinChang Got a reply from Facebook team, that it it's fixed. But I still see wrong numbers in analytics.

And I don't see any related commits for this issue.

https://developers.facebook.com/support/bugs/515260065544773/

any ideas?

I'm experiencing the same issue as well with v7.16.1 :(

[Kendja]

Updated to v7.17.1. Now revenue shows wrongly by 10x+ up to 20x+.
Using Unity 2019.1.8f1.

@KylinChang @dreamolight my bug report on https://developers.facebook.com/ was closed as resolved. And they don't reply anymore there.
Please, check it out.

I have same problem. Last facebook sdk and Unity 2019.1.8f1.

[andreyfaraponov]

have the same problems,
Facebook SDK 7.17.1

[eladleb]

I am experiencing a similar issue but only for iOS, using 7.17.2 @KylinChang is anyone from your team looking at this...? It makes the SDK unusable.
Every other analytics product we have reports accurate numbers except for Facebook's Unity SDK :(

[Kendja]

@bobob89 @andreyfaraponov @eladleb I submitted another bug report via facebook:
https://developers.facebook.com/support/bugs/391897685015143/

If more people will comment under this report maybe they will fix it faster ;)

[KylinChang]

Hey @eladleb @Kendja , do you use the latest Unity SDK? Have you tried other versions of Unity SDK?

[eladleb]

@KylinChang Yes, I'm using the latest unity sdk. We suspect the false iOS revenue numbers are coming from users who are using a pirated version of the game as it seems that there is no server side receipt validation when reporting Facebook Purchases?

[Kendja]

@KylinChang yep. Both different versions of unity and different versions of this plugin has been used since April

[drallcom3]

v7.18.0 The issue still persists. Bug reports about it on https://developers.facebook.com/support/bugs/ get deleted or marked as "fixed", which it clearly isn't.

[Kendja]

Same. But now also iOS revenue is shown wrong by 2~3x times

Unity 2019.2.11f1
vFb 7.18.0

[bobob89]

Still have it too.

did you need a specific permission to view the analytics debug? I'm an admin on the facebook dev console roles, am logged in to the personal facebook account on ios facebook app on device, but I still do not see the events appear in the debug on Events Manager? Did you need to add any code for the Events Testing to work please?

EDIT: I HAD LIMIT AD TRACKING ENABLED ON IOS SETTINGS, WHICH PREVENTED EVENTS TESTING FROM WORKING

[mehves-veloxia]

Still experiencing this issue, it is tracking both iOS and Android purchases wrong by ~10x+ for both platforms.

SDK v7.19.2 (latest now)
Unity 2019.2.21

[dlees]

I'm seeing the same problem after upgrading from Unity 2019.8.3. Only my iOS purchases are duplicated. I don't post the events myself (turn off auto revenue tracking results in 0 revenue shown).

SDK: 9.0.0
Unity:2019.4.11

Has there been any fix for this?

[mastef]

Is there a guide on how to replace the broken auto inapp tracking with manual inapp tracking?
