We are changing the registration process for new users to the app. You can now use email invitations to bring users in. The sent email includes instructions on how to register for the app and, most importantly, a button to confirm registration.
With invitations, you can not only easily direct users to the app but also set the necessary permissions in advance. The invitations also include a bulk import of users.
Don’t worry, for existing customers, new user registrations will work as you have been used to for now.
