We recently integrated MetricKit into our app; however, the 90th percentile data does not seem to match the data in Xcode Organizer. The values reported by MetricKit appear to be higher. Additionally, it looks like data for previous app versions is not being updated in Organizer as adoption of the latest version increases.

Has anyone else experienced this issue? Could there be a delay in data updates for older versions in Organizer? Are there any known limitations or best practices for ensuring consistency between MetricKit and Xcode Organizer data? Any guidance would be greatly appreciated.

Xcode Organizer only shows data from devices that have consented to share data (via the "Share with App Developers" switch in Settings > Privacy > Analytics & Improvements). This can be a subset of what you're capturing through MetricKit, as MetricKit data isn't gated by the privacy setting. If the discrepancy between Xcode Organizer and MetricKit data is larger than expected, please file feedback at feedbackassistant.apple.com and share the FB number in this thread.

Although metric data for older versions continues to be aggregated, it tends to stabilize in Xcode Organizer as your users move onto newer versions of your app. If this is not what you expect, could you tell us more?
