I am struggling with a few things on the Odoo e-learning module on version 16.0:

Adding attendees - This isn't working on either Chrome or firefox. i invite an attendee - get an email to send out. The email is not arriving nor can I adjust the user to reset the password etc.

The Course banner header is now white and the text is also white so I can't see the course title. 

There is nothing there when I log in as a course participant to check what my learners see and how they can navigate to their course.

I looked through various support videos but can't see anything that addresses these issues.
