Items not displaying offline in firebase based Android chat app [closed]

I am beginner to mobile app's development. I am trying to develop a chat app like WhatsApp with the help of online lectures and youtube videos. I was successful in developing it and connecting that to firebase. What I had noticed is that while when my phone is not connected to internet my app is not showing details of groups and other stuffs. Even after enabling data connection it is showing the details after some time delay. While connecting to fire base database for the first time I had selected server location to default (US). I am located in India. Whether this distance is causing the problem in delay in getting the items
