Sean Q.

kapa.ai I think I figured it out. Is there any way I can see the most popular combinations of platform for these users? For instance, how many were Web / iPhone or iPhone / Android?

kapa.ai It does appear to be a second-level aggregation function, but not a first-level selection. So I can do distinct count within Average, Sum, Distribution, Median, Percentile, Minimum, Maximum. Notably Distribution is not in the documents as a first-level function but is in the UI, while distinct count is in the UI as a second level function but not as a first-level one.

kapa.ai I don't see Distinct Count as an option for aggregate property by user -- just Average, Sum, Distribution, Median, Percentile, Minimum, Maximum. Would it be Distribution?

kapa.ai I don't see Distinct Count as an option here:

No problem -- we figured out a way to do this with Custom Inherited Properties, but yeah, it's a bit more of a lift than the holding constant option.
