It's strange to me that the dragging the slider gives no indication whatsoever that anything is going to happen.....then, just as you said, the Shortcuts section just suddenly starts to reveal itself. Thank's so much for explaining the trick with this. It's been driving me crazy since the last update that I couldn't work this out on my own.
Has anyone seen any explanation or resolution for this issue? I've confirmed that the Shortcuts list is still available in the Windows, IOS and Android clients. My Mac is my primary machine so it's extra annoying that it's suddenly gone from only this platform.
