Open the first message in the list

In the past few weeks, something changed to where I no longer have the option of having the first email selected when I navigate to a folder in Outlook (desktop or web client).

There used to be an option in settings "What do you want us to do when you open Outlook?" that had a setting of "open the first message in the list", but that is now missing.

How do I get that option back? Is there some setting I need to enable to make that option come back?  I know the new UI is being forced on us now, but I haven't seen anything indicating that this was a feature that was removed - the option of not having it auto-select the first message was always an option as well, so I don't understand why a way to toggle between the two is no longer present.
