It appears that Epics are being replaced by Parents. Here's a screenshot:

It looks like all of my tickets have been modified to move the Epic value to the Parent field. That would be fine, except that I can't search for tickets with In Progress Parents like I used to be able to search for tickets with In Progress Epics. The following JQL query used to give me what I want:
project = DevOps AND "Epic Link" IS NOT EMPTY AND "Epic Status"= "In Progress"
What am I supposed to do now? I see that JQL can query based on "Parent Link" but not on "Parent Status".

Am I having a permission issue, or has this capability simply been removed from Jira?
