How do I find duplicated sheets in Numbers?
I am using Numbers 11.1 (I can't seem to update on my iMac using Catalina 10.15.7). I have a file with several sheets; but, when I go to duplicate one of the sheets, the new sheet does not show up along with the other tabs. This has happened before, but the duplicated sheets would eventually appear (up to several minutes later). But now, they are not appearing at all. What am I doing wrong?
