Hello - My name is Sharon and this is my first post here. Always been a Mac person, but this is my first iPad! I started playing around with it last night and like many people found it hard to put down! I do have a couple of questions - and go easy on me, I'm middle aged! Do I turn it off when done using it or just let it go to sleep? I turned it off last night. This morning, it doesn't seem to want to "read" my fingerprint, and I don't think I assigned it a passcode, unless the passcode is the same as the password or username on my MacBook pro, but that doesn't seem to work, either. I'd like to go back in and assign a passcode if possible. I promise to not ask such simple questions in the future - I leave for East Africa on Thursday so need to have some basic info really quickly, and did not find much support on the Apple site. Any help would be appreciated. Thanks, folks!
