The domain format from the app is diferent to that one the second step is waiting for. My app domain was "8080-5930a92a-9aaa-421d-af9f-b8c74b7d2063.us-east1.cloudshell.dev" and even when the exercise works, I had to add the domain "8080-dot-2999129-dot-devshell.appspot.com" in firebase console for getting 100 for the score.
something is wrong with the checks, I can't get it green. Also, the password has to be more than 6 letter, I had to bring the dev tools to figure it out.
