Error from Companion: For a custom firebase host you must first set your authentication server before using authentication features!

and my firebase url and api key already right but i not find what is problem

I actually don’t quite understand this error because I’ve never seen it before.

Can you show us how did you user firebase blocks?

Do you use api key and url in designer mode or in blocks section?

Yes… create a new project with us-central as location and do the same thing
