Yes, you should be hearing the audio from the example sentences in Reviews. This should be true for both the newly added audio and the older recordings. We are not sure what might be preventing it from playing on your end. Do you have Bunny Mode activated? How about autoplay? The next time you get an N3 review question that should have a recording associated with it (the example sentences have audio) without any audio, would you mind taking a screenshot and reporting it here? Cheers!
@walkerranger Thank you for drawing this to our attention! I have straightened out the audio for べつにない. Cheers!
