How to permanently disable Focus Inbox

Hi All

I'm hoping someone will be able to help me out with this. I've tried to searching online for this but haven't been able to find a permanent solution.

I would like to permanently disable focused inbox so none of my emails are sorted. I find the focused inbox annoying and have missed emails because of it.

I know how to change the settings through View > View Settings > Email. I have done this multiple times and the very next day or even later the same day it goes back to sorting my emails. 

My email addresses are Google and Micosoft based that I have all set up in Outlook so that I can see everything in one location.

Is it possible to permanently disable the focused inbox feature in Outlook for Google or is this something I'm just going to have to live with?

Any help is greatly appreciated. Thanks.
