Hi - we're really struggling with this. We're reviewing Bittle for UK National Coding week and so far, haven't managed to even get onto the desktop app. This is the message we're getting. On a Macbook Pro Running Monterey 12.5.1 Can you advise please?

OK — thanks — will try again. We've been following the video tutorial that came with the Bittle — using the QR code on the sheet.
