Hi Doug-

We would need more information to draw a conclusion as to what is causing the issue. \
Keep in mind scheduled messages do not leave the schedule store if they are \
registered on a cron job or have a really high repeat count.

If you have a reproducible unit test and/or specific stack traces from a log, that \
can lead to a resolution.

Best to first rule out any configuration or coding error by the application.

Hope this helps.

Thanks,
Matt Pavlovich
