I was trying to build a custom report following this thread http://sitecore-community.github.io/docs/xDB/reports/extending-experience-analytics-reports/
but I'm stuck that segments table of reporting database is not populated I followed many qustions and solutions for example this thread Reporting Segments table not being populated 9.0.1
I deployed marketing definitions, I rebuilt the reporting db, I have no errors in logs
Sitecore 9.0.1 (rev. 171219)
however I still see the segments table empty, any clue about this?
