We know about that one
Clicking on the ear / headphones icons doesn’t work for me either - I have to click on either their name or their picture for them to appear.
Hmm. Maybe there’s some confusion or I have the same problem.
I don’t think the little headphone icon is clickable. I don’t think it ever has. I agree clicking on the main avatar or the username brings up the audiogram for me.
FF on W10.
To the best of my recollection, I used to be able to click on the headphone icon for the audiogram. Now not. But the main avatar or username works for me.
Ah, happy we figured this out! Confirming, headphones have never been clickable.
