After upgrading to SharePoint 2016 we noticed that the Usage.Requests table in the PowerPivot Service Application database is not being populated.
all the other tables are storing information, but that one remains empty
Also the usage.Documents is not populating the document metadata like owner, filename, last modified, created, etc.
This wasn't mentioned on things deprecated by powerpivot, could something cause a problem to extract that data into powerpivot service application database ?
