Hi @pexlechris, thanks for your question.
The reports are scheduled to run at 16:00 UTC, but will run during the first non-cached hit that occurs to your site after that time. WP-Cron is typically triggered by a visit to the site so could run much later on a site that doesn’t have much traffic.
We don’t currently have a way to schedule them at a different time within the plugin, but some customers do disable WP-Cron and run the jobs at a time that suits them using a scheduled task on their server. There are tutorials out there that explain how to do this, but it will affect all plugins on your site that use WP-Cron so should only be done if you’re comfortable with making those sorts of changes.
Thanks,
Peter.
