Ffirst challenge: Run Test button doesn't proceed to next challenge

I’m at first challenge, which is:

<h1>Hello World</h1>

I typed everything correctly and clicked Run Test, yet didn’t proceed to next challenge.
Also, nothing on the emulator phone screen.

I’ve edited your post for readability. When you enter a code block into the forum, remember to precede it with a line of three backticks and follow it with a line of three backticks to make easier to read. See this post to find the backtick on your keyboard. The “preformatted text” tool in the editor (</>) will also add backticks around text.


Code looks fine. You may have to close the browser and come back in or refresh your browser and try to the run the tests again.
