We apologize for the issues. We’re currently troubleshooting Blockly and it is our top priority. If you’re having issues, we recommend using Snap! instead for now. If you could provide us with as much detail as possible — the machine and operating system you’re using, what exactly has been happening, screenshots of your Blockly workspace, videos, etc. Any information you can give us will help get Blockly up and running again. Thank you!
