AppsFlyer - Data Mismatch

Update timeline

1. monitoring Mar 17, 2026, 03:05 PM UTC

   AppsFlyer - Inflated monetary values Monitoring - A recent update to our AppsFlyer connector caused a regression that greatly inflated monetary values, specifically Cost and Event Revenue, for any data that the connector retrieved between March 16th 10:05 AM and March 17th 12:04 AM (both times UTC). A fix has been deployed, and we believe that the majority of affected AppsFlyer data sources should self-heal within 24 hours. If your data source is still showing inflated values for these metrics after 24 hours, or if you want us to manually refresh your data source(s) to expedite the process of getting your data corrected, please reach out to our support team. We apologize for the inconvenience.

   We have observed that some data sources are not self-healing as we previously anticipated, partially as a result of quota limit constraints that cause the re-fetching of affected data to take longer than expected. Moreover, we have identified that some data sources backfilled more historical data than we were previously aware of around the time the regression was introduced. We are currently working to locate these data sources to ensure that they are scheduled to re-import any data that has been affected by this issue.

3. monitoring Mar 20, 2026, 03:23 PM UTC

   We have now scheduled new backfills for all AppsFlyer data sources and date intervals that we believe to be affected by this issue. Due to quota limits, the process of re-fetching all this data may take a bit of time, but we hope that it will be completed over the weekend. We will check progress on Monday and update this incident accordingly.

4. monitoring Mar 23, 2026, 03:28 PM UTC

   We believe that most affected data sources should now have correct data once again. Some data sources that have a lot of data to re-fetch may still be in the process of backfilling historical data, so we will continue to monitor for a while longer. If you still notice any discrepancies related to inflated monetary values in your AppsFlyer data sources, please reach out to support and we will investigate accordingly.

5. resolved Mar 25, 2026, 10:06 AM UTC

   We consider this issue to be resolved. Backfills for affected data sources should be completed successfully by now. If you observe any inflated monetary values in your AppsFlyer data sources, please reach out to support for investigation.
