LiveUI button will not toggle off once it is active
I'm running 8.1.3 and logged in with SysAdmin rights to a Developer portal.
When I launch another portal I see the "LiveUI" floating button at the bottom. I can toggle this "on" and use it to find info on the UI. However, I cannot select the button again to toggle "off". I've seen this behavior only in one of our custom portals that was upgraded from 7.3. I am not seeing it happen in the OOTB Work and Case Manger portals. Any ideas what could be causing this to happen?
