We have a process where:
- Issue-A is created via the portal
- Automation fires an email to an external party with Issue-A in subject
- Reply via email is received creating Issue-B
- Automation links Issue-B -> Issue-A
- Copy info from Issue-B into Issue-A comment
I'm currently trying to automate copying information from Issue-B into a comment (5) on Issue-A in isolation, eventual aim being to chain them if that's possible.
If I manually trigger a link of Issue-B to Issue-A the automation fires and populates the comment:
- Select Issue-B
- Link - relates-to - Issue-A
- Comment added to Issue-A
However the {{triggerIssue...}} fields don't appear to be accessing the data in Issue-B.
Here's the rule:

And the resulting comment generated on Issue-B:
TriggerIssue: Issue-B
Issue: Issue-B
Reported by:
Summary: Summary of Issue-B

Any help would be appreciated.
