I have a first-gen iPad Pro with the smart keyboard, and I went from *zero* keyboard connection problems to literally having to try six to a dozen times or so to get the keyboard and iPad to talk to each other literally overnight after installing iOS 12 a few months back.
I've been patient, assuming it was just a small bug that was introduced along with the several colonies of bugs introduced with iOS 12, but every dot release that comes out just seems to make the keyboard less reliable.
I used to travel with my iPad for convenience, giving presentations or taking notes, generally -- but after once or twice looking like a maniac disconnecting and reconnecting my iPad from its keyboard a dozen times in front of a room full of tech folks who just absolutely drool over every little thing Apple doesn't do perfectly ...
I've lost my train of thought, but all of that to say this: three years and 26 pages of this problem, and still no solution? Has Apple even acknowledged there is a problem here, or should I take some GENIUS advice and restore from backup and try again, like my iPad is running Windows 95 or something -- it's really quite pathetic and a frillion percent NOT PROFESSIONAL.
