Learn to code 1 module is not showing the puzzle on the right viewport. I can write commands and run them, but the puzzle viewport is just blue. Skipping through the lessons I can get maybe 5 of the puzzles to show up.
When loading the puzzle viewport, playgrounds will automatically try to run code and fail. On the puzzles that show up, it won't try to run code after the initial loading. And the puzzle works just fine.
