I installed the new version and opened a project which I created with 2.0. The files have been converted. Now I changed background color, the color of some bottoms and made them glossy, generated application files and did the preview.
Everything works fine if the project just consists of 1 page. If you have more than 1 pages and switch between the pages
the old background color appears and it is not glossy, etc. – Just the old version comes up again.
