At the first try 1.2 was not certified for the marketplace. The testers are doing a great job and did find a theming issue with the light theme and an unhandled exeption. I have uploaded a fixed version for a second try to become certified for the marketplace.
I also fixed an issue with the assigning of a template to a new group. As workaround you can assign a template over the “edit groups” menu after adding a new group. Add a new group, save it, then go to the menu page and select “edit groups“. Then select the new group you have added before. You can select a template by the bottom application bar.
Sorry for the delay.
