I’m double clicking into the master symbol like I have in the past to edit it, but when I try to duplicate one of the items with alt-drag I get the error:
“This element can’t be moved.”
When I select the inline text link in the Navigator and copy/paste it to duplicate it, I get the error:
Copy: “Cannot copy root symbol.”
Paste: “The clipboard is empty.”
Any idea what could be causing this?
