WhatsApp keyboard language change idea

Here's a little bugbear of mine: iOS autocorrect turning WhatsApp messages into stroke-symptom gibberish simply because I'm trying to type English words while the keyboard is set to my native Polish, or vice versa. At least iMessages remembers the language of each of the conversations – WhatsApp does no such thing!

A couple days ago I thought "Why can't the dictionary and suggestion popover work as a language switch?", fired up Framer and prototyped a simple solution for this problem.

Multilingual designers, immigrants, friends – does that little keyboard issue bug you too?
