Login App with Firebase

Hi everyone, I need some help. I was trying to make an app to login for a school project following this tutorial: https://appinventor.mit.edu/explore/ai2/firebase.html
It shows everything(photo here

), but I cannot press Sign In and Send Verification Email buttons. If I write something as email test and password test and then press Sign Up, nothing happens.
Thank you for helping :slight_smile:

Can you please send me the aia? Also, two years ago, when I made my first Firebase login app, I followed this tutorial. I think it might help.


Why are you using a Web Viewer?
