Hi Chris! I tried it out just now, and it's working.
Nothing has changed on our end, and I'm using the latest stable Chrome, with httpseverywhere enabled, and a vpn on.
It could for you still be browser extensions or settings. Check into that. For example, I have a rule that disables my uBlock Origin, as that interferes with courses, and also I ensure 3rd-party cookies can be set by the course, as that can cause issues as well.
If that doesn't help, please
- post the url of the challenge that you couldn't pass (just in case it's not 2.3);
- And also post a screenshot of your full browser (address bar, full width) showing at what point you can't type.
I can then start by trying to reproduce and can help you out further! Also, while waiting for help and so you're not stuck, use the Toggle Navigation button (or Table of Contents button) at the top of any in-course page to move forward to other challenges.
