We have 3 JIRA next gen Projects that make up our platform components (Web, Mobile, Backend), and we want to make a fourth project to house the higher level features as epics, that would then have all the children stories from these other three projects linked.
Currently however, when I try to link a Story from another project to an Epic in another, JIRA seems unable to find them/build the link. Am I doing something wrong, or is this functionality not currently available?
