Webinar Panelists not able to log in for practice session

[Kilrwat]

My panelists are receiving the panelist invites, but when they try and sign in, they are told they need to have a Zoom account in order to do so.

Do panelists need to have a Zoom account? While I get it from a marketing perspective, as a user, I find that strange.

Welcome to the Zoom Community, @Kilrwat,

Do you have the Require panelists to authenticate to join option enabled in the Webinar?

If so, see the requirement indicated that they must be logged into a Zoom account.  Uncheck this box, and they should be able to enter the Webinar without a Zoom account.
