Co-organizers and/or Administrator can't start Webinar

Hello,

...since last week some Co-organizers and/or Administrator within the organization can't start a Webinar, only Host or Super-Admin can start.
In settings the "Allow Co-organizers within the organization to start the webinar" is set.

What's the problem. Please check and help. Thank you.
