Hi David,
These two learners do not have more courses than many of the other learners who do not have the issue. They are middle of the pack so to speak with course load.
Also we use Totara 12.8 and users login to their dashboard which does not show all their courses or the navigation menu.
The profile is slow but the dashboard and home screen will actually timeout if there are a lot of users online.
Thank you for sharing that though. It is something I can look at as a comparison point between users.
Peter
