Unable to get OTP code through Firebase Authentication feature after Uploading to playstore

I used the same apk before uploading to playstore. At that time OTP verification process was successful. But after rolling out to playstore I installed the app, now firebase otp verification is not working.

The problem is same app in playstore is unable to generate OTP

I believe you should replace it only and I mean only the SHA1 value

Nothing… in the firebase console, just add a new one, and it will work.
