Is an Articulate account now required to post comments?

Hi,

Our learners are having trouble posting comments for a Storyline course without an Articulate account.

Your documentation says only an email address is required, however, our testers are being asked for a password.

I have checked the box to allow users without an Articulate ID to post comments. Please see attached.

How can I enable this feature, it has always worked before? Thank you for your help.

From your documentation:

By default, anyone who has a link to a project can review it and post comments—no account required. They'll just be prompted to enter their email address when they post comments so they can receive notifications for replies.
