I cannot speak to any of the underlying reasons or decisions made regarding this game-changing release. What I can say is: It is now so slow and clunky as to be practically unusable. I use a Premium version for my business and since I’m on iPad 95% of the time, I can’t see a way to be “running the older version.” A few nice minor features were added; other, more important ones were lost (ie: simplify formatting). But the overall usability has suffered: It is slow, slow, slow, slow, slow.
