Describe the problem/error/question
When I use N8n to nest a loop within a loop, after my child loop node finishes running, it starts executing the second iteration of the parent loop node. However, when it triggers the child loop node again, it defaults to only executing the “done” phase and skips the “loop” phase.
What is the error message (if any)?
FIRST FATHER LOOP:
BUT THE SECOND FATHER LOOP:
