If your Adobe plugin is not working as expected, one of the possible reasons might be that a "stuck" session or a cache conflict is preventing the proofs from loading. Try clearing the cache to see if that repairs the issue.

If the problem continues after clearing the cache, try reinstalling the Ziflow plugin in your Adobe application to see if that resolves the issue.

1. In Finder, go to Go > Go To Folder…
