i had some phone support from Apple today because my iPad air2 had to be reset/restored after it went loopy last night! It wouldn't recognise my modem. I finally sorted that problem out myself and once back online discovered iPad asking if I wanted to restore from iCloud, android (which I don't have!) don't have an iPhone either. No PCs here, only iPad. So I wanted to start as a brand new iPad and with help of support worked way through the stages, electing to add things like CC later. however once support call finished, I discovered yes I'd finally got some original iOS 8 apps back, like camera and FaceTime. Couldn't access my iCloud mail either though the app was there. Don't know what the tech did remotely but yes I then had my mail working properly.
Also restrictions which I hadn't put on last year, we're now off thank goodness. So now iPad telling me yes I'm on ios9.3.1, but I've also still got original passwords, and CC details all of which should have been deleted when I watched the delete process While talking to Apple Support Tech. So why are they still there and where has my little grey circle gone that was always on screen and I could change orientation with - so what now? Is there a solution! iPad tells me it's all up to date, when it obviously isn't!
