We were unable to replicate this issue on browsers except for Internet Explorer and Firefox, so if you were to use Chrome or another browser in the interim for a fix, you'll be able to access menus there. 

Unfortunately, Internet Explorer and Firefox are both minimally used and increasingly unsafe (non secure HTTP) which affects priority for updating, we'd advise using Google Chrome, Safari, or another equivalent modern browser as a workaround until the new changes can be fully implemented across browsers.
