I want to enable *Inbox by Gmail* for my Google for Work account. This page tells me that it's available and how to find the checkbox to enable it. <https://support.google.com/a/answer/6082718>

I followed the steps provided on that page, but I don't see the checkbox *Inbox by Gmail* within Apps > Google Apps > Settings for Gmail > Advanced settings > End User Settings

From my Gmail account, I already sent an invite to my Google for Work email address.

Do I need to wait a bit longer or is the checkbox to be found somewhere else?
