This just started late last week for me. While editing request types, when I click on preview for either the "Request Form" or the "Issue View" they both take me to the Request Form in the the portal.
Clicking on "Issue View" should take me to what you see when you look at an individual issue in Jira Service Management, but this has stopped working for me in both my company instance and my personal dev instance.
Any ideas?
Also, when clicking on configure in the bottom right corner of a record in my project, when it takes me to the Request Types / Issue View screen, this does not match up with what is actually being displayed on the screen/form while I am in an actual record.
