I am trying to avoid excessive notifications from Trello and Butler. As the admin, I am able to set "Change Notification email frequency" to "Never". Then I created the following automation rule:

This works when I run the rule. When I have another non-admin user change the notification frequency and create the rule on their account, it does not work. I though maybe it was because of the notification rule, but in my test case...I change the rule on my account to send the email message to them and they receive the email.
Any suggestions on why other users cannot make this rule work for them like it does for me?
