Hey Patrick_R , apologies for the delay in our reply and thanks for replying and letting us know the issue has been fixed.
Currently a lot of code in our standalone (the frontend as well the editor) has changed compared to our previous WordPress only code (version 2.9 and before). We added quite a lot of new features since version 3.0 and removed deprecated code (minimalizing our bundle size).
I think we'll update our legacy code eventually in the future, but currently our focus is on developing new features for our standalone first.
If there's anything else we can help you with, make sure to let us know! 🙂
