Recurring invoices not working

Hello,

I have a customer that is set up for a recurring invoice to be created for them each month.

This feature has worked properly just once after I set it up about 2 months ago. The invoice doesn't automatically email to them, which I think should be an option for this feature, but the first automatic invoice was created correctly last month.

But I checked just now and this month's invoice for my customer hasn't been created.

Does this feature not work after a month even though the end date is set to indefinitely?

Thanks,

Kylie.
