I recently was messaging a host on airbnb and noticed some small papercuts like the Enter button not sending a message (adds a newline instead) and sending a message doesn't scroll to the bottom so I sent the message multiple times unknowingly

So given this, I assume well for their bottom line but not as well for UX

I think they actually merged PMs and with Product Marketing Managers rather than with designers[1]
