The current scheduler for Quarantine summaries is either Never, Every x hours, Daily or Weekly. The summaries are coming out just shortly after midnight and, since many people have e-mail on their cell phones, they are getting woken up and complaining. If we go into the settings and click on 'save' then the summaries can come out at a different time.
It would be nice to set an actual time or several like 8:00 AM and 6:00 PM
Thank you for sharing your idea to allow the time of daily quarantine reports to be configured. It will be considered for future versions.
