I have multiple "Features" and to that multiple "Features" there are multiple "Stories" linked to them. These multiple "Features" are linked to an "Epic". Now I need to find the linked issues of those multiple "Features". I'm able to get linked issues of a single "Feature" by using the JQL ( issue in linkedissues (ABC-123) ). But I want to get linked issues of multiple "Features". So, I tried with the JQL ( issue in linkedissues("ABC-123", "ABC-246", "ABC-456") ). But now this one fails to get the linked issues of those multiple "Features".
