Zero non-default keyboard support – Quip - Docs, Chat, Sheets Review

This is absolutely unacceptable and makes this app unusable for anyone who doesn't use default keyboards. I use Google's keyboard (GBoard) for English since it's got much better auto-correct, but whenever I use the Quip app it only allows me to enter Korean because it's the only language in which I'm using Apple's default keyboard. Yep I can only input Korean characters in Quip. This is 2018 Quip, what's wrong with you?
