Hola Inma, There has been an issue with the "Play Audio" button on the dictation exercises for the last few days. Sometimes it sticks on "pause" after clicking "Play Audio" and at other times it doesn't respond to a click.
Specifically it has happened to me on "Breakfast the most important meal of the day" y "Energía todo el día." Can you ask the techies to look into it please? Saludos. john
