Sessions metric doesn't coincide with the Breakdown

Reports and working with data
6

Hi @Piotrek , thank you for your reply. I’m being pushed about that my management everyday and I will appreciate if this update comes ASAP.
However, the same problem is true for other GDS controls using filters, when I interact with Piwik Pro. For example,
Piwik Pro shows the following:

Sessions and visitors - Custom reports - Analytics
Sessions and visitors - Custom reports - Analytics1229×303 26.5 KB

Sessions and visitors (edit report) - Custom repor
Sessions and visitors (edit report) - Custom repor1333×589 27.3 KB

and Google Data Studio shows the following with the same filter

Dashboard_EU_Marketing Internal POC v1 › Website T
Dashboard_EU_Marketing Internal POC v1 › Website T1835×501 51.6 KB

  1. What value is the right one(in Piwik Pro or in GDS)?
  2. Could you please let me know if there is any way I can reach the same values in those 2 platforms?

Thank you,
Dmitry
