A client continues to receive automated invoice reminders even though reminders are disabled at the client level.
Automated invoice reminders can be controlled at both the client level and invoice level. Disabling reminders at the client level does not automatically update existing invoices, so invoices created earlier can still have reminders enabled.
To resolve this issue, turn off automated invoice reminders at the invoice level. To do so, open the Invoices screen and filter the list to show invoices for the affected client. Select the relevant invoices on the grid, then click Actions and choose Batch Update. Set Automated Invoice Reminders to Off and save the changes. When updated, automated reminders will stop for those invoices.
