Depending on the order specifications, your digital item may display as pending until it has been fulfilled.
Digital items with a pending status are typically released after about 24 - 48 hours. Most newly purchased items are accessible within 1 to 2 hours, but it could take up to 24 hours.
EDO or Awaiting Fulfillment items that are codes can sometimes have an availability stating, "will be added to digital bookshelf within 5 to 7 business days". Please note this can't be expedited, as it means we are awaiting the code from the publisher.
