Hey, I think I have the same issue. I cannot expand the panel, and the “Create Variables” button is hidden. I’ve tried it on web browsers, both the Windows and macOS versions, and they all seem to have the same bug.
Got the confirmation from the Technical Quality Specialist that the issue should have been resolved now. 🥳 I can also confirm from my end that is everything working properly now. 🎉 Happy friday and designing everyone 🔆
