Hello @Malcolm Schonfield
Thank you for reaching out, and welcome to the Docusign Community! We appreciate your question and assure you that we are fully committed to providing you with the best service possible.
The "Allow recipients to create a Docusign account" setting is the correct setting to disable post-signing account creation invitations. However, changes to account settings may take some time to propagate. Since you've already updated the setting and tested it, I'd recommend trying again after some time. Please note that the Signing completed destination URL in Branding only controls the post-signing redirect and does not suppress the account creation prompt.
