Some Zephyr Enterprise users cannot open attachments

Hi, 

There isn't a specific permission that will block a user from viewing attachments within a test case/project. I'm wondering if this could be a setting on user's browsers that's possibly blocking the popup? and are you still having the issue? 

If everything checks out with the browser settings and you're still experiencing this issue, please enter a support ticket - Zephyr Enterprise: New Support Request
