Have you opened Blackboard lately and found that your menu is missing with no way to retrieve it? Some users, depending on the browser and device they were using, had this experience and it left them unable to navigate their Blackboard site.
After testing the problem and checking in with Blackboard, we determined there was no easy way to fix the problem across all platforms. So, we made a global change and have disabled the collapsing menu.
Thank you to everyone who reported this issue so we could do some research and come up with a patch while we wait for Blackboard to implement a longer term fix.
