When accessing Query Analytics in PMM for the host, where there are no slow queries logged yet, message "There is no query data because the MySQL Server is not configured for monitoring." is displayed.  As soon as there is any slow query in the log, the message disappears and queries are displayed.

This behavior is misleading, as the configuration is actually fine, so would be better to display a more specific message like 'slow query log does not contain any entries yet'.
