When I click on the refresh in box it starts but keeps running? What is wrong?
Try clearing your cache.
I clear it daily, so that is not the problem!
As a check, try using a different browser and see if the same thing happens.
I am observing the same behavior.
When I click on the "Refresh Inbox" icon, the two curved arrows that chase each others' tails start rotating clockwise, and they continue to rotate counterclockwise until I force my browser to reload the page.
I observe the same behavior in the latest versions of several different web browsers, including Safari, Firefox, Chrome, Opera, Brave, and Vivaldi. Clearing the caches of these browsers has no effect.
As a work-around, what I have been doing is to use the reload-the-web-page button or icon in my web browser's menu bar while the browser is displaying the contents of my In Box.
