I would like to view PDFs from a URL within the app, the same way you can view PDFs which have been saved to a DB object in the display-image component. Is this possible with the latest PDF updates container 4.80?
This is not possible at the moment, unfortunately. (Basically this has to do with modern Browsers having built-in PDF readers, but the app does not)
You will need direct access to the PDF files / data in the app if you want to view them in the app.
You can make a suggestion on our roadmap to include the ability to view PDFs in-app from app accessible URLs
