Today after upgrading to Premium, i installed the wixdesigner extention in VS2019 Community (16.9).

After restart of VS, it displayed that VS does not load wix designer extention as it apparently is accessing outdated API.

I installed the current premium version you can download today from the add-in express website. So i uninstalled the extention and restarted VS. Error gone.

Is there a update coming to fix this or how to solve this?
