We are currently using Adobe Designer and Central pro 5.7. We have the following critical issue.
When earning statements are deliverd DIRECTLY from our adobe server and opened in the native mail client in IOS8,7, or 6, the PDF is rendering as blank or a message is being issued that says "not a valid pdf file".
If we forward that same email, the PDF shows correctly. I can also successfully VIEW the pdf on the server, prior to being emailed electronically.
Our security admin feels that there may be something in the encoding of the PDF when its directly emailed from the server to the recipient.
What / where should we look. This is become a critical issue as more and more users are going mobile with apple and cannot view their earning statements.
