The problem Bansira Mobile Banking solves

It's an internship project that i made. I cannot share github repo code for this but you can visit playstore to check it out.
Problem it solves:

• Shows all your transfers, history, mandates and etc.
• Acts as MFA and verifies user by his/her fingerprint, faceID or password.
• When some MFA requiring changes are made on web application, user is notified through push notification.

Challenges I ran into

The problem about sending push notification to users.
I was using expo push notification which worked in development build but did not work in production build.
Later i realised that that for expo push notification to work in production build, expo required Firebase FCM API v1 keys.
When i uploaded the FCM key to my expo account, push notifications started working.
