I’m not sure how to post this due to security, but this is what I did:
1. Configuration for new form.
2. 1 tab with fields from the list
3. 1 rule set to run when the tab is loaded (but did not work with load/change either), based on the unique ID (I also tried with index too), with some of the fields set as required.
When I ran my test I had only one rule set to run. I turned debug on and even though the criteria matched, debug showed it did not run. It does run as expected on edit form, though, same rule with same settings.
