Reader XI is the standard at my office and is installed as the default PDF handler for most users. We have an issue where one of our users updated to Reader DC, and while they were able to view and fill out a form in Workspace, they were not able to submit it. Is Reader DC incompatible with Workspace?
The form uses the process fields object to submit.
I've noticed similar situations where Adobe Reader DC will not properly apply Reader Extensions to an enabled form. I've also seen issues with Adobe Reader DC not printing properly from the Reader plugin.
No, it has not been resolved. Right now we are neck deep in developing an LC project so more research on our end has been put on-hold; I posted this here hoping that someone had encountered the same issue, or that perhaps someone from Adobe would see this and could get us the information we need.
For the user in question we had them uninstall DC and reinstall XI. Our agency has a policy of keeping pretty up-to-date with various versions so I know we are going to have to address this further at some point in the near future, but we haven't gotten there yet.
