Design mode not working for Rapid Developer Course app.

Hi everyone, Is anyone else experiencing issues with the design mode functionality in Mendix Studio Pro? For me it displays the loading circle in the bottom left corner, but it continues to load endlessly. I am currently working on module 10.3.1 of the Rapid Developer Course (Developer), but have also noticed it when working on previous modules. I have always used the latest version of the project as provided in the resources. When trying to use design mode with the Start Your First App template it loads within seconds.  Looking forward to your experiences.

Are you using Mendix 8.1.0? If so there is a known issue with this version. Mendix will be releasing a new version, 8.1.1, shortly to fix this issue.
