Adobe Extended Features

I have Aspose.pdf.kit for .Net. When I flatten a pdf file and then try to open the pdf, I receive a message stating that "The document enabled extended features in Adobe Reader. The document has changed since it was created and use of extended features is no longer available."

Is there a way to keep from getting this message?

Hi Stewart,

Please try to use the latest version (4.9.0) of the component. If it still doesn’t resolve your issue then please share the input PDF file with us, so we could reproduce the issue at our end and guide you accordingly.

We’re sorry for the inconvenience.
