As for the underlying issue, I have experienced similar typing issues on my iPhone in recent months. It feels like someone changed the keyboard to optimize for some typing behavior that doesn't match my own, so the "optimizations" work against me. It's reminiscent of when the US Air Force redesigned their cockpits to match pilots' average measurements, only to discover that using averages just made the cockpits bad for everybody.[1]
