I'm guessing your Firebase database is not in us-central1.

https://taximotofix-default-rtdb.firebaseio.com/

The Firebase component only works with that server location.

I checked and it's us-central1. I did another one to be sure. But it still shows a white screen.

I'm stumped.

Do you have any secure rules set ?
