The keyboard on my iPad has just started floating and so is now much smaller and very difficult to use.
How do I get it back to go full size on the bottom of the screen. Note the way described in this Apple document https://support.apple.com/en-us/HT210758 does NOT work. Spreading fingers on the keyboard does nothing. Ideally some non gesture way as I find gestures are impossible to remember.
Secondly how can I stop this from ever happening again?
