Distinct count per day from 2 tables summarized by period

Hi, 

 

I'm new to Power BI and are looking to create a report to track product engagement over time.

For that I would need to track active users per day, week & month and compare those with the previous period. I'm having issues creating a formula that can display the distinct count of users PER DAY from the 2 tables.

 

I'm tracking active users from 2 tables (Feature Click & Page View), 1 user can appear in both tables on the same day, in that case the specific user should only appear as 1 count. 

 

I've tried using the formula below, but it doesn't seem to "reset" for each day and thereby doesn't allow comparisons to previous periods.

Distinct Count Page & Feature =
 COUNTROWS(
     DISTINCT(
         UNION(
             VALUES(Fact_Platform_Feature_Click[Platform_User_SK]),
             VALUES(Fact_Platform_Page_View[Platform_User_SK])
         )   
     )  
 )
 
Example data
Table 1:
Table 1Table 1
Table 2:
Table 2Table 2
Result I'm seeking:

@Christoffer_B , Create a common Date and user tables and join both tables with these two tables.

 

Now create this measure and plot it with a common date column

 

measure = Countrows(Distinct(union(Distinct(Table1[User]), Distinct(Table2[User])) ) )
