Watermark doesn't disappear although I added the licence key

Hi there,

Thank you for contacting pdf.js express forums,

Please note that in development mode (i.e. localhost) the watermark will always show up.

One common reason this happens is when you have different pdf.js packages (i.e. having both viewer and pro versions when you should only use one)

When loading the viewer under your domain, could you provide any console error messages if any? Here’s another forum post where it was solved via unblocking csp headers:

Best regards,
Kevin Kim
