Reading Pane in Outlook for Mac changes when App is re-opened

I noticed that today, whenever I close my Outlook for Mac and then open it up again, it opens with the reading pane on the bottom of my list of emails, as opposed to on the right-which is how I always have it. Even when I change it, by going to View-Reading Pane-Right: when I close Outlook for Mac, it reopens with the reading pane on the bottom. This has never happened before and has only been happening today. Does anyone know why this might be? I am using Version 16.102.2.

Many thanks!

    It could be a bug in that build, I saw another person mention it but he just said outlook, not Outlook for mac.

    I'm using an early release build, it just updated to 16.104 and cannot repro it in this build. I rarely quit Outlook so did not notice it last week when I had 16.102 builds.

    Do you have Help > Contact Support? If so, use that to report it. Thanks.

    Rolling back to October 20 release should fix it.

    I don't know if you can use mixed versions - trash the office apps then install the oct 20 version from that link.
