I noticed a few weeks ago so of the buttons on the left hand side have changed or lost functionality such as when in a workspace, you usedt to be able to click on the name of the workspace on the left hand side and navigate to different reports from there. Those are gone. I have tried clearing cache and logging out and back in but that did not work.
Here is an image i copied of what the buttons used to look like:
Notice how test workspace has the option for a drop down and would display reports. Now the blow is my naviagtion pane:
Obviously the copied image before this was a little older but still you should understand that the functionality is missing from the button.. This is important as there was a workaround to allow you when testing security of a dataset to switch between reports in a workspace to test as role where now with that function missing it is just defaulting to the first report.
