Mostly Apple’s fault

I like this app, but for some reason each device goes back, randomly, to the Apple default keyboard. That is really annoying. As to the problems that people list about grabbing every letter that one scrolls over, that’s not my experience and it seems to be impossible. Who could have tested it and how could anyone use it—as I do.
Weirdly, it plays havoc with numbers, turning a few numbers into a set of unrelated ones. Nothing in the list of replacements gives any hint as to how this happens.
