Unity FB SDK - Android app installs reported not adding up
I'm sorry this is not strictly Unity-only question but Facebook Ads Manager's own support only helps with the Ads Manager configurations not in finding issues in using their Unity SDK.
We just started to advertise 2 days ago our new Unity Android game with Facebook Ads. The problem is that we only see 266 installs reported by Facebook Ads Manager for the 2 days while both GameAnalytics AND Google Play Store's own reports show 490 installs. Since GameAnalyitics report matches almost exactly the one reported by Play Store.
Before the ads started we had near zero oganic downloads and even now Play Store says 97% of the installs come from 3rd party referrals (not organic). And we only advertise on Facebook. So all our installs should come from Facebook Ads which means the installs they report should match the installs reported by Play Store. In brief, I guess the issue is Facebook Ads Manager under-reporting the installs but I don't understand why and how to troubleshoot this and find the problem.
Facebook, on their side technical support says they've made some tests with our game's ads and all looked fine, 'no abnormalities'. But I can't have them check if my Unity SDK had any implementation errors (followed the official instructions though it was ok in the past). Unless there's a bug or incompatibility in one of Fb SDK vs. Unity version. I'm using Unity 2019 and FB SDK 11.
I know in iOS 14 one can opt out from reporting but this is Android so every installs should be possible to track and there shouldn't be such a big difference in Facebook's and Google Playstore's reports.
Any idea what could be behind this or what sort of implementation or configutation error may result in such a difference?
