You could try a forced re-start of the iPad. Hold down the Home Button plus the On/Off button, ignoring the power off option - until the screen goes black. Release the buttons when you see the apple logo.What causes the Home button (physical button) to be unresponsive sometimes after several pushes on certain programs? Is the iPad Pro 2 (2017) taking its time thinking? Sometimes 10 to 20 seconds. How "normal" is this delay? This is a "new to me" refurb.
