New Gboard dual language suggestions, how do I disable it? Recently the Google keyboard has activated suggestions for both of my selected languages.  This is a real nuisance since the suggestions are a mess IMO.

How can I disable it and go back to switching languages manually?
How can I get back to manually switching between languages? Is there a
  setting I've missed, or do I have to roll back to an earlier version?


On the the keyboard options you'll find settings for Languages, Preferences, Theme... and in Text correction you'll find the toggle you're looking for: multilingual typing.
