There are issues with purchasing a course twice because the customer is registered in the list with the date of the first purchase, not the latest date. The problem arises in the form of old emails, which are no longer part of the automation process but have been corrected in the meantime between purchases and being sent to the customer. This is very confusing and appears highly unprofessional. I was advised to create new lists. However, the issue is that I don’t know when a customer orders the course again. I’ve only discovered the error when old emails are sent together with the new ones. This must be fixable as a 'list problem.' I assume the CRM system keeps track of the rest of the customer information.

And I also see another issue too.

Is it possible to reset all the modules and lessons in the course portal for every customer who is "revoked" from the course after they receive the last email after a year?
