As per your comment on the old ticket: “However, if you can provide an error message that originates from PDF.js Express , please feel free to share it in a new thread and we can investigate further.”, I am generating new topic for my IE11 Webviewer issue.
PFA of webviewer does not loaded in IE11, and showing some “Invalid Character” Error, most probably due to the pagination numbers not loaded fully.
Please note that, The Webviewer is successfully loaded on Chrome, Firefox, Edge, Opera browser., however does not loaded in IE11 and Safari browser. Also we have upgraded PDFjs Express with v.7.2.
So, If there could be a issue in my application, then it should not work in other browsers too, however it has been working fine except IE11 and Safari
