Hey, I'm facing the same problem. Did you find any solution or workaround? Thanks.

Hi, I'm having the exact same problem. For the daily API reports I read that the completeness of the data is like 5 days after the target date. However, even after waiting that time, I'm still having different values for the Installations and Deletions. Did you find any solution or workaround to this? Thanks

Hi, we are having the same problem here. I’m using the API to get "App Store Installations and Deletions (Standard)" report. By reading the documentation, I understand that daily reports reach completeness approximately five days after the target date and that you should only consider valid the latest report that contains your target date. However, what I don't know how to handle are the discrepancies between the API report: "App Store Installations and Deletions (Standard)", the "First Time Downloads" results, and the data from App Store Connect website Analytics > Usage > Installations. I understand both are subject to only "opt-in" users. However, in the results I get from the API I see lower numbers than the results from the App Store Connect UI. Which ones should I consider as valid?
