I had opened the following case and received the answer that Report
Builder with version 2.0 is still under development :
push to have this release be sooner rather than later!
Hello!Data extracted through Report Builder does not match data that
appears in Workspace.I read that "The reason for the discrepancy is that
Report Builder uses API 1.4 of Analytics whereas Workspace uses 2.0."It
is hard to explain discrepancies to clients; could we get an idea as to
when Report Builder is planned to be upgraded to the newer API version
