When you are not logged into your account, Kopernio's functionality is restricted and it will always default back to "No PDF Found" and you will be requested to log in and redirected to the login page.
After logging in, you will be taken to your Kopernio home page, which is your Locker (PDF storage).
Once you are signed in, you will be able to continue your literature search.
Please note, you will see this if you are browsing in incognito mode as Kopernio is restricted by default. You will need to enable Kopernio in incognito mode.
