FireBase takes so much time to authenticate or do any query in Firestore while using 4g Mobile Data

Question

The problem I have with Authentication is that it takes up so much time and returns the result maybe after 10 minutes. I ended up skipping the authentication most of the time in my app using the manifest file.

With firebase firestore I am unable to get any data back and the log with Firebase filtered gives me below.

2022-11-03 05:30:59.981 453-473/? W/TransactionTracing: Could not find layer id -1 2022-11-03 05:31:00.114 453-473/? W/TransactionTracing: Could not find layer handle 0x7f187c234bf0

Kindly refer to the below codes and please let me know if I've done any wrong implementations.

Am I using the correct imports?

    mAuth.signInWithEmailAndPassword(userEmail,userPassword)
            .addOnCompleteListener(new OnCompleteListener<AuthResult>(){
                @Override

                    if(task.isSuccessful()){
