I have made my application and published it to google play store. I used Firebase Phone Authentication for verification members, before I released it to the play store it worked fine, but when I downloaded it from google play it throws an error saying:
(this app is not authorized to use Firebase Authentication. Please verify that the correct package name and SHA-1 are configured in the Firebase Console. [App validation faild])
I also added App Signing of SHA 1, SHA 256 and Upload SHA 1, SHA 256 of my application in google play console, but unfortunately, it doesn't work.
