As mentioned here, to increase the 6mb limit on Android.. try this:

in MainApplication.java add these lines in onCreate function

  public void onCreate() {
    // ...
    long size = 50L * 1024L * 1024L; // 50 MB
    com.facebook.react.modules.storage.ReactDatabaseSupplier.getInstance(getApplicationContext()).setMaximumSize(size);
  }

Answer 4
