"PDF.js Express Dev mode" still appearing after valid license

Which product are you using?
PDF.js Express Plus

PDF.js Express Version
UI version |‘8.4.1’|
Core version |‘8.4.0’|

Detailed description of issue
After purchasing a PDF.js Express Plus license, the red watermark “PDF.js Express Dev mode” is still visible after editing a PDF file.
That error happens on the build of my registered domain

On localhost, I receive this message
PDFJS.express: Development environment detected. This license key is currently registered to ‘domain’”

So I assume the license is valid. But the watermark remains

Expected behaviour
That the red “PDF.js Express Dev mode” watermark is not visible

Does your issue happen with every document, or just one?
Happens on every doc

Hey there!

A separate license key is required for the REST API which is why you’re seeing that error. Please get a API key on the dashboard and provide that to the REST API.

Thanks,
