Office 365 Adoption

Hi,

I have installed Office 365 Adoption content pack. In "Skype for  Business  usage" I have data/statistics but when I go to "Skype for Business - user activity there is no data

I also connected directly via OData to https://reports.office.com/pbi/v1.0/<tenantid> 

Tables: UserState and UserActivity are empty (rest tables have data)

What can be reason that this data is missing?
