How come, on my cell phone, it is possible to click "can't hear right now" which will turn off the questions requiring audio, but on the desktop at the library, I don't have that option?
Maybe that is because on your phone you are using the app, and you get can get new updates. At the library, the computers are ancient and probably don't have that sort of thing. It also doesn't have that choice on my laptop, so maybe it is just a phone thing. Mantener el buen trabajo! (Keep up the great work)
