Reply to Analytics Reports API response only returns empty data array
Hi Christian. We're seeing a similar issue here. I'd recommend trying to bring data from different dates and see if you can find anything. From our experience, there are multiple reports with weird gaps on the data. I opened a similar thread here in which Apple said it might have to do with their Privacy Thresholds, but their explanation isn't consistent with the amounts of data we have. Following this thread to see if there's any solution on this.

It can be multiple things. Make sure you're comparing apples to apples: there are multiple metrics for "installs" and you also have multiple dimensions (country, apps, device, product page, source, etc). More often than not, that's the actual problem. I'd review my data closely and look at their docs to make sure you're looking at the same thing. Privacy thresholds: this could be it indeed. What you can do here is to avoid the "Detailed" report if your app is too small. I hope this is helpful.

Got it. So first thing I'd do is to check if the data matches if I don't have those filters (US and App Referrer). If it does, then it's probably the privacy thresholds. This is what the docs say: "Data in the framework’s reports is aggregated, and similar users are in groups, which means individual user data is not easily identifiable. To balance data privacy with usability, the framework applies two approaches as needed to specific reports: Thresholding Omits values with data from fewer than 5 users or 5 unique devices. Noise Adds a small random number to metrics. These privacy measures maximize utility as the volume of data increases, while also helping protect users identities. The framework applies the same privacy measures across daily, weekly, and monthly reports for the same type of content, ensuring that utility increases as more data is collected over longer periods of time." Full wiki here: https://developer.apple.com/documentation/analytics-reports/privacy Apparently "5 unique devices" is the bare minimum. But the noise part is more unclear, on that link you'll find the calculations on how they apply the thresholds, but I also don't fully understand it tbh.
