Auto selecting first email not working

Within the past few days, something changed in Outlook web mail where it no longer automatically selects the first email in whatever folder I'm in, and instead forces me to select something manually.

I've always just opened webmail and it defaults to the inbox and auto-selects the first email listed, and I have the reading pane set to show on bottom.  Something changed in the past couple days to where that no longer works.  No matter what folder I go to, nothing is selected, forcing me to manually select the first email in each folder.

I looked through the entire settings area, and I don't see anything to adjust this.  Searching online, I see options of "What do you want to happen when you open Outlook", but that may be part of the classic layout options because in the new UI, I don't see anywhere to adjust this.

All I want is to have it go back to the previous behavior of auto-selecting the first email in the folder (inbox or any others) when I select the folder.

How to I set it back to that behavior?

Also to note - in Outlook desktop, it works like it always did (when I open the desktop client, it defaults to the inbox and has the first email auto-selected so I can view it in the pane below), so this appears to only be in webmail.  I've tried re-sync, cleared browser cache, and even across multiple browsers, but they all do the same and won't auto-select the first message, so it appears to be some setting in O365 on the web/cloud side, I just can't figure out how to change it.
