I'm working with my VAR but we are having a major issue after upgrading the Adobe to Adobe DC where when you click on the 'LF thumbnail' it does not change the display.  You have to use the Adobe page up and down features.

Also, they have redacted many things, but the redaction is not showing up on the LF pages.  You see that there is something there but it is not 'showing' on the document.  You send it and it does not show the redactions.  Something with the redaction tool is getting lost. 

Please respond for any 'fixes' ASAP.
