I have tried to end a couple of recurring invoices. It says it was successful, but they remain active. Refreshing the list doesn’t help. It seems the only way to stop a recurring invoice is to delete it (and perhaps by archiving it … which I’ve not tried).
This occurs in the Mac app, and in browser.
UPDATE: Even after archiving the Active recurring invoice, it remains with “Active” status in the archive. no idea if they are going to send out new invoices when due to.
