My iPad Pro was supposed to be less quirky because it runs iOS and not a full OS, but I'm finding almost as many quirks as my Windows 2-in-1s. Sometimes I lose the ability to hit Cmd-H, Cmd-Tab, and Cmd-Space (basically everything I use for switching between windows). I am on iOS 9.3.4. Sometimes this happens when I am running Slack simultaneously, but sometimes not. But more often when Slack is running. I thought it might also be my SSH client, but it also happens in Word. Does anyone else have this issue?
