I've just installed Qlik Sense 3.0, very happy to see the new major version of this tool I'm trying to "sell" to my users.
I had hope about new feature or bug fixes on the stories and discovered that there was a new style : Right Aligned Sheet.
I have tested that and, guess, what happens if I choose a left aligned sheet and a right aligned sheet ? when exporting to Power Point or PDF, both types are left aligned... Only the text changes the side.
Is it the same for you ? if the same, I can't believe testers have not seen that... And I don't talk about all the bad formatting in the PPTX or PDF
