We use a number of customised ad-hoc reports that are scheduled either daily or weekly to send to admins. These have worked fine for a number of years but having just updated 2 sites to Moodle 3.6.2+ this past week, the emailed reports are now not being emailed out.
I have checked and all reports are being generated by the Ad-hoc report plugin. I have also checked that other emails are being sent out from the site (ie password reminders, certificates, etc) so it doesn't appear to be an issue with the emails.
Cron and scheduled tasks are all running correctly also.
Are there any known issues with the ad-hoc reporting and the latest version of Moodle that I should be aware of?
