            recyclerAdapter.notifyDataSetChanged();//notifiy us if data has been changed.
            recyclerView.setAdapter(recyclerAdapter);
        }

Na classe de atividade, o adaptador firebase é implementado. Por referência ao banco de dados firebase, as imagens são carregadas apenas com o ID "-LO061DOhjG2hVZlqY79", mas com IDs como '01' '02' não estão carregando

Adapter está carregando imagens muito lentamente Saída deste código

Ajuda será muito apreciada
