We've moved all courses and content to a new platform. You may have become aware of this when you were forced to set a new password for the new site.
The new site will automatically put you in the correct group based on the domain in your email address, so you no longer need a group enrollment code. You should just have access to your courses.
We've tried to copy over everyone's progress in the course but there may be some accounts that didn't come across correctly. You can mark sections as completed manually to get yourself back to where you were.
Send a message to training@coan.co if you need help.
