We are pleased to announce that the ability for users to "create an account" from the Business App login page has now been restored for all partners that have it enabled.
Optionally, channel partners can remove users' ability to create an account by hiding this button.
Go to Partner Center > Administration > Customize > Business App > and check the box for “Disable "Create Account" on login page”.
If you have any questions or concerns, don't hesitate to get in touch with our support team.
