Loop Returns transformation fix

An issue with how Loop Returns data was being processed caused return figures in the Returns dashboard to be under-reported. This fix applies to BigQuery merchants only.

Some return records were being excluded during daily updates, causing the Returns dashboard to display lower numbers than expected.

We corrected the data processing logic so that all return records are accurately captured during each update cycle. Returns dashboard numbers may increase slightly as previously missing records are restored — this is expected and reflects your actual returns data. No action is required.
