I was trying to use the "In Query" operator for applying a filter based on the result set returned from Query within Insight Individual filters. But for some reason, the insight does not pull any records when the filter is enabled. And I am pretty sure that insight should be returning rows after the filter is applied.
Version - 5.1.4 (on-Premises)
To debug such an issue please follow these steps:
1-Create an insight showing the data as the expected results from the inquery filter syntax.
2-Create another insight for the main result set
3-Export both of the 2 insights to Excel files to be able to match the data.
