I’m noticing that when I open chat on my iPhone X and go to type, the chat input box isn’t bottom aligned to the keyboard. In other words, there’s a gap there that throws me off a little. I’m able to scroll the screen down so that it will align, however, I think I expect it just to be bottom aligned.
I’m not sure if it bothers other people, I just know it bothers me 
I could probably fix it with CSS but I do imagine others may feel annoyed by it, too.
