## Reconciling against the vendor's own dashboard

**Where to look in Instagram's own dashboard:** find this metric (or its components) under the relevant report/section. Confirm the period boundaries and any filters match the Vortex IQ profile to reconcile cleanly. The Vortex IQ value may legitimately differ due to period definition, time zone, sampling, or how the vendor buckets the underlying records.
