Note that the puzzle piece on the image itself is not movable. You would need to move the arrow below the image and not the actual puzzle piece.
If that doesn't work please try a couple of things as mentioned below:
- Delete your cookies/cache on your browser,
- Try a different browser,
- Try using private/incognito mode.
If the problem still persists, please contact our support team with a screenshot of the error that you might have received.
