Hey folks, long time lurker here. Picked up my 11” Pro yesterday - it’s a beauty alright, but just want to check something with you all, as I haven’t owned an iPad in many years. Holding down the power button... doesn’t bring up the slide to power down. Is this normal? It strikes me as odd. Sleep / wake by button works fine, obviously it turns on, and I can shut down by selecting it in settings. So the button seems to work... just that long hold doesn’t register. Am I being dumb or is it a defective unit? Thanks!
