I have 3 perspectives that are all the same that I cannot remove from the sidebar. Its driving me nuts.
Support are working on it, but I wondered if anyone else had this problem. See below.
What I did was star the perspective and it showed up in the sidebar. But when I deleted it without removing the star, it stayed there. Support told me to recreate it and then remove it first before deleting it. When I did this, i just kept getting another version of the perspective in the sidebar.
