Hi Andy,
Thank you for your feedback.
In the new Edocman version 2.0.0, we've integrated the PDF viewing feature directly into the component (no longer relying on external libraries as in previous versions). As a result, some small adjustments may be needed to ensure the preview works properly on your site.
Could you please create a support ticket under the "Edocman" category and provide your site URL along with a super admin account? I’ll check and help you adjust the PDF viewing function accordingly.
Best regards,
Dam
