Aggregate Help

[wallace0834]

I need some assistance in writing an expression or aggregation of the total number of employees who has access an App or Sheet within the first 30 days of the Operational Monitoring.

Count({[Access Date]=(AddDays(DayStart(today())-30)),{[App Name]=("*")} > } distinct UserId}) or 

sum(aggr(count({<[Session Count]={1}>} DISTINCT [App Name]),MONTH))

May be something like this

Count(DISTINCT {<[Access Date] = {"$(=Date(Today()-30))"}, [App Name] = {"*"}>} UserId)
