Yeah, something happened a few months ago where by iOS I'm now "hitting" the wrong key a lot, words like we'll and we're are constantly being automatically "corrected" to well and were and, most frustrating, it will auto"correct" the last word in a sentence from what is on the screen when you hit send. It went from almost always helpful to often frustrating.
My “favorite” version of the last issue is trying to acknowledge with “K” which inevitably becomes “I”.
