I made this a while ago, just give it some practice. This is an HS issue, I cannot adjust how much you have to swipe down or how fast.
Reload (exit tab or project and come back). HS Webplayer is acting up
Tips: Use a mobile device, release your finger after the swipe, HS measures how much you swipe, not how fast. When you release, HS will register the swipe
