Google Assistant Routines gone from your phone? Check this

Oh no! No Routines!
If you are having trouble like me with the Google Assistant Routines disappeared from your settings in the Google Home app, try setting the language for the assistant AND the phone to English (US) and nothing else.
Then restart the Home app, and you can find the routines tab again. Make sure that the Google Assistant on your phone you want to change the routines is ON, too. Otherwise again, the routine settings are gone.

I'm really having enough from all this crap with the Google Assistant that needs workarounds everywhere. This is not intuitive.
