Hi Craig,
Thank you for your reply and confirming the booking details change trigger is only set off by a change in the date and time. It is level of detail that i couldn't see in the Totara documentation, as i had found both pieces of guidance you sent.
Is there any more detailed guidance, about how to see the times (when and how often) each notification will run?
At this point i'd better asked if the centralised notifications timings, would be different to the course level versions?
In other words if i am not using the site version of a notification, and i have adapted it at the course level, will the enabled courses versions go out / run with the site versions.
Thank you for your help so far.
