Compilation of Smart Values within Linked Tasks

[Bryan Harmon (Lost Boys)]

Hello there!  I'm attempting to compile a list on a top-level task and running into an issue with automation.

For context, this top level task has several linked tasks, each with a Smart Value "Patch Note." 

My goal with the automation flow is when its transitioned to an In Progress state, it enumerates through each linked task and compiles a list of Patch Notes from each linked task.

The issue I'm encountering is that I'm unable to access the latest comment of the root top-level task via any Smart Value I've tried to edit it with the compiled list of notes.

I've tried using {{triggerIssue.comments.last.id}}, but this yields "No comment to edit."

Thanks in advance for any information you can provide.
