App Tracking Transparency (ATT) is Apple's framework for requesting access to a user's IDFA. If you use any of our attribution integrations, this article will explain what you need to do to make your app compliant. What is App Tracking Transparency (ATT)?

It’s a common issue that comes up on every single analytics platform - in one system you have 3105 active trials, on another, 5046. What’s the deal? These discrepancies are common, and can happen for a variety of reasons. This article covers why you can expect certain discrepancies between RevenueCat's analytics and other platforms, and what you can do if things don't seem right.

If the sources are different, then you should expect differences in the data as well. RevenueCat only collects data that is sent through our in-app SDKs or REST API - there's no connection to any other so

App rejections are an unfortunate and dreaded aspect of launching a new app. It’s bound to happen at some point, and in the case of subscriptions and in-app purchases, it’s usually not something that you or RevenueCat can resolve. RevenueCat can’t contact Apple on your behalf and we can’t expedite the review process, but we can help you troubleshoot the rejection and work toward a resolution. If you’ve read through our docs on rejections and are still having issues, read on. Background / Review Environment Unfortunately, Apple’s sandbox environment is notoriously flaky - there are regular outages and sometimes purchases can get hung up in their system. Most of the time this error is due to sandbox downtime, but you can read about all the causes for this error in our guide on error handling. Even worse is that Apple’s reviewers use this unstable environment for App Review, which can cause issues when the reviewer tests in-app purchases like subscriptions. The App Review team typically d
