OK, I reported it at https://bugs.kde.org/show_bug.cgi?id=331665 (doesn't Launchpad have some facility to track bugs in upstream?).
At other times the Check for Updates option did appear in the More menu after muon-updater downloaded latest information, and this didn't take very long.
The good news from the KDE bug report is the bug is probably fixed in muon-updater 2.2 series.
