Firebase Error in The application

[Taifun]

I have created an app for my IOT project by using MIT app inventor, it works fine In AI companion , but when I installed its apk file in my phone then the app is not Starting

concerning the first screenshot "For a custom firebase host you first must set your authentication server before using authentication features" you already received the answer to that error 3 times... how many times more do you need the answer before adjusting your settings? [Unbenannt] Taifun
