I have previously been able to utilize the "Link Summary" option in JQL to query linked issues by specific link types (see example below)
project = "Portfolio" AND "Link Summary" !~ "relates to" AND status = Active ORDER BY priority
After using this JQL for quite some time, I just received an error message on that query that states: "Field 'Link Summary' does not exist or you do not have permission to view it."
It appears this field was deleted at some point recently. How can it be recreated?
