NativeFirebaseError: [auth/internal-error] An internal error has occurred, please try again.

[arTJs j]

I'm using react-native-firebase package for my project. After very long hours i have been trying to implement fb auth into IOS app. 

However I get 

[Error: [auth/internal-error] An internal error has occurred, please try again.]

This project runs in the web, now I'm building a app that should use the same provider.

I have checked in the log explorer in google console but it gives no errors regarding auth/internal-error.

 For a test I have created a empty project and just pasted new config into the app and it works without any problems whatsoever.

I even removed all my cloud functions to be sure it's not it.

I don't see any reason why it wouldn't work. I have checked online but people have some random problems such us not turning on of email password provider. Anyone have idea if there is any place in the google console where I could debug it or get some more informations? Or even better knows what's going on..?

The only thing I see that's different is the face that one project uses Identity Platform and other out of the box doesn't but that's probably because my main project has Blaze plan.

I also don't want to create a new project to fix this issue because I have whole thing running on it. Can't move.

I have created ticket at google but I think they won't help me.
