Dear, 

I am new to Power BI. 

Could you please to provide me the tutorial of how to build Cohort Analsysis in Power BI?

I used to make CA in Tableau, and now my job requires me to build CA in Power BI. 

I searched on google how to build CA but not many sources taught CA in Power BI, there is 1 source but I have to pay fees. 😞 

I hope you could help me

Thanks so much!!
