Converter Failed seems to be issue with MSoffice
Story Telling is not dynamic, if you take snapshots it only for the selections which you made at that point.
it will not change dynamically for next months.
Thanks a lot for your answers.
Such a shame that Data Story Telling may not be dynamic, it's a real need.
I am facing the Converter probIem using MS Office 365 2016. I will investigate in Microsoft forums but it probably is a Qlik Sense problem (nobody is able to open the pptx generated, whatever PPT version is used)
