It relies on cron/senddigests being run in order to do this and "daily"
is whenever cron/senddigests runs and could be "twice daily" or "Mon,
Wed and Fri" or whatever depending on when cron/senddigests runs.

Either they were only getting digests when the size threshold was
reached, or if they were getting them daily at a specific time, then
something was running cron/senddigests at that time.

You need the cron job because nothing else in Mailman sends digests
periodically. The only other mechanism sends a digest when the list's
digest.mbox exceeds a certain size, which may not happen for weeks on
a low traffic list.
