We've been pulling daily download reports (First-time downloads + Redownloads) via ONGOING requests and noticed random missing days in our data — in April alone, we were missing the 11th, 14th, 23rd, and 27th.
After debugging, here's what's actually happening:
Apple sometimes publishes two consecutive ONGOING instances with identical content (same processingDate → same Date in the CSV)
The day after a duplicate, the CSV skips a date entirely — that data is simply never published
Those missing days are gone forever. There's no way to recover them via API
Does this happen to anyone else? Do you know if there is a way to recover missing data?
