Her mic was peaking, meaning the input volume was too high, which caused the distortion. Definitely hard to listen to. Plus, that squeaky "okay" was unacceptable. I'm wondering of the soundtrack was off for anyone else. It's upwards of 12-15 seconds off which made the overall instruction hard to follow.
the mouse cursor pointing the button and the explanation is not matching the same speed. May be if she slows down a little bit to match the mouse cursor speed would be better. Thank you for the post though. It still is very helpful!
