PDF Expiration Dates Extended
When you ad-enable a PDF, you may notice that there is an expiration date associated with each file. Upon hitting the expiration date, the PDF will be displayed without ads. The purpose of this expiration date is to prevent "orphan" PDFs that do not have a long shelf life from proliferating. This week, we have extended this expiration date to ~ 2 years for every PDF ad-enabled through the service. As a reminder, you will continue to receive email notifications prior to and on the day of the expiration date.
