'Not able to fetch data in react-native app from firebase after generating signed apk

I have recently generated apk from my react-native application project, I have used firebase to store data and authentication, before the generation of apk, I was able to fetch data from firebase to my application but after I generated apk, it is not fetching data.

The problem is most probably related to sha key which I have changed but still, the results are same.

Please help
