Email / Google signin is fail. It says firebase API not correct. Google signin fail.
I guess other builder is working fine. I am waiting this for long time. 
How strange, Email/Password and Google SignIn work normally with me. It just doesn’t work in Companion (as expected), but if I build the app it works.
Pra me estar funcionando normal nada uma foto dos blocos pra ver o que estar errado
create a new project and try. It says api not correct, google signin fail. i donot know how to do now.
I did some tests and it works fine for me 
Do you want to show the blocks? Or is it possible post any .aia with that error?
