As you may have already read, I was facing some issues connecting my Expo React Native app with a Firebase database in order so that data from the app can be added on the Realtime DB and vice-versa.

I've already completed the sign in/up authentication process successfully, but once the user enters the app to interact with it and create data, these data can't be updated to my Realtime DB.

Here's the link for more info: https://snack.expo.dev/@eliagjika/cfa-assign-4

Thanks to anyone who can give it a look! 🙏
