HUGE bug in Beta

1

I got all the way to the first project after jQuery which isn’t that far so I tried the Beta since I wouldn’t have to make up much progress. On the very first HTML one with Hello World i did what it asked

Hello World

and pressed Run code, it ran and printed it successfully but the green run code button was stuck green and wouldn’t let me move on. I then manually used the map and it showed as incomplete, I clicked the second one and the same thing happened.

Are you using Firefox or Edge? Because if so I believe it’s a known bug that’s been flagged up on GitHub. I’ve come across the same problem and so am having to use Chrome to work through Beta.

I use Edge. That might be the issue.
