Does it work if you make it recurring?

Hi Anton,

I try to set a daily calendar in https://demo4.traccar.org/

And connect the calendar with reports like this.

I expected to receive a report email at 9:20 AM on 6/28 but did not receive it.

I use the "Test Channels" in the notification page, and I have confirmed that I can receive the test mail.

You have a daily report with more than 2 days period. It won't work like that. You have to have at least 15 minutes between events in your calendar.

Thanks Anton, it can work on daliy recurring after I update the calendar.
Still can't set recurrence to once.

Once doesn't really make much sense to me, but feel free to create a ticket for it. Make sure to include some use cases for it.
