I do not understand why the Backerkit infrastructure wasn't used to deliver the PDFs. Your websites store just does not want to work correctly. Any attempt to login to my account, which I had already before backing this, results in a "There has been a critical error on this website." WordPress error. This happens after wiping my cookies, my cache etc. It happens in different browsers even. It happens if I use incognito mode even. This is incredibly frustrating.
