Is there a shortcut for closing all the open tabs in Chrome browser on an iPad? Last time I checked, which has been a few years now, this function was available on the iPhone, but not on an iPad.
Is this still true? If so, why is it still missing after so many years? I can't imagine a technical obstacle to implementing this feature.
Force-quit Safari (double-tap the home button, then tap and hold on the Safari icon until it shakes, then tap the red minus sign).
Go to Settings > Safari.
Tap Clear History.
This should clear out all open tabs.
I was able to fix it by unchecking "Show Dashboard as a space" in Mission Control Preferences. No idea when exactly this change happened or why this fixes it though. 
I would have preferred to be able to just re-map the shortcut, but I can't find it anywhere.

In the upper right-hand corner of Chrome for iPad is a square with a number in it. That number is the number of tabs open.
