On the Customer Details page the Content Access tab lists all products a customer currently has access to.
To adjust the dates a customer has access to a product, click the Edit link next to the product in question. You can then enter the Start Date and End Date you would like to use. Click Update to save your changes.
The expiration date is always based on the date of the order or import, not when the account is created or the user logs in.
Access is always calculated at the time of purchase. If a product access duration is changed, customers who purchased previously will still have the same, original access.
Using this feature allows you to extend or shorten how long your customer has access to a product. Please note the Content Access page will list a complete history of access based on all customer's purchases/assigned access. As such it is expected that some customers may have multiple entries for a single product in this table.
