At step 29 the type=‘checkbox’ got removed and it shows a text field.
I doubt it’s a bug, you’ll fix it in further steps as you progress.
Yeah, it got fixed on the next step but I just wanted to let them know.
It looks like this was fixed and merged about four days ago. It’s actually showing as a checkbox for me, so I think the fix has made its way to production. You might have an old copy cached in your browser?
