I had many artwork/flyers created using Adobe Express. I loved it. Now that I had to forcefully import my artwork to this new upgraded Adobe Express, it got completely distorted - aspect ratio, fonts, shapes, elements, color palette scheme etc.
There have been recent updates in the Adobe Express webapp, and these updates may resolve the issues you've raised. We'd also like to apologize for the frustration caused and inform you that we are continuously working on enhancing the app experience.
