QuickBooks Online has changed the Subject Line of the emails sent for new invoices, and ignores our Default selection.

Our DEFAULT selection has had this format for years:

"Invoice xxxxx from ECS Distribution"

Even though we have selected a specific default subject line, QuickBooks online started populating the Subject Line field with this new format:

"New payment request from ECS Distribution, LLC - invoice xxxxx"

The attached screenshot shows QBO acknowledges the default Subject Line, but is still populating the Subject Line with something else.

Does anyone know how to force QBO to revert to the Default Subject Line we've always used?

Thank you
