iPad tells me I MUST change my "unlock passcode at this time"
my iPad is giving me a pop up message forcing me to change my passcode. It will not let me do anything unless I change my passcode and does not give me an option to do it later. I haven't been able to use my ipad for 3 days because I can't go past it and I refuse to enter my passcode into the pop up message because it looks fishy... I have heard/read about a similar problem with the iPhone with an option to do it later, but haven't seen anyone talk about this with the iPad. Please help. I last updated my iPad about a month ago and have never had any issues with it. It's a personal iPad (not corporate)
iPad Mini, iOS 9.3.1
