I'm currently setting up conversion tracking on Firebase and Facebook for mobile marketing campaigns, but the tracking confuses me entirely. It's my first time promoting an app with a subscription model, and even Google, Apple and Facebook themselves struggle to answer my questions. Maybe one of you is able to help me out?

* Where do I see the revenue I got from *newly* subscribed people in a specific timeframe on iTunes Connect?
* Does Firebase and Facebook track Trials also as in\_app\_purchases?
* If a user subscribed and paid after the 7 day trial, will he only then be counted for an in\_app\_purchase and revenue event?

So far, Facebook only tracks some revenue and purchases, but not even a 10th of what I'm actually making, but I also don't know how to compare Firebase, Facebook and iTunes Connect as the numbers are so extremely different. Your help is much appreciated.
