@slartibartfass thank you for reporting this issue. I unfortunately don't have the time and energy to invest into it. But, this plugin is really simple, what it does, is just modifying the config.ini.php file: https://matomo.org/faq/how-to/find-and-edit-matomo-config-file/ and to edit the following line: scheduled_reports_truncate = 23

--> Would this solution could work for you?
