Event scheduled reminders not sending with fixed date
I've been doing a bunch of testing on this on my site running Civicrm 5.13.5 and Drupal 7 after my event scheduled reminders were not working.
And after posting on stackexchange it was replicated on 5.17.4; Drupal 7.67 by ericg
From what i can work out, if the original reminder has a fixed date (eg, 19th Sept 2019) the first email goes out but no subsequent repeats go out. No errors in the cron log.
But if the original reminder has a date like "1 hour after event start date", the repeats work.
The steps I used to reproduce were:
- Make sure cron is working and schedule reminders set to hourly
- create a test event
- make a scheduled reminder with fixed date and repeat every hour till a year after event start.
- only the first reminder is delivered
- set a reminder with relative date (1 hour after start date) repeat every hour until a year after start date.
- works as expected.
