Can't move to the next Curriculum Challenge

I’m trying out the first curriculum test which is the Basic HTML and HTML5: Say Hello to Elements, but when I click Run Test nothing happens, it just states Running Test. There’s no prompt to move to the next challenge.

The challenge tests do not work well on Safari, Edge, or Internet Explorer. The curriculum works best when using Chrome.

Let us know if you are still having trouble when using Chrome.

It works fine now. Thank you!!
