Processes in Microsoft 365 Insider for installing preview builds, activating subscriptions, and keeping apps up to date with the latest Insider features.
Hi MikePugh2,
Hope you are doing well!
Have you ever tried the steps suggested by one of our MVP moderator? You will need to report the problem as much as possible for this to be notify with our developers for Office.
However, if you use the Menu Bar and choose Help > Feedback > Report a Problem and describe what's going on with the Excel update from the server and that the other apps update as expected, maybe someone on the Microsoft side can reset the server.
Best regards,
Bo
