You need to remove “Action is updated” then it will work.
This condition means that a note or new reply was inserted. You only need the condition “Owner has changed” for your trigger to work
Thank you, now it works.
Whats the difference between “Article Last Sender” and “Customer”? I used the “Article Last Sender” because it was in the examples, but would like to know when is better to use customer.
Article last sender is used in triggers where you want to react to a new note or e-mail reply. The sender of the e-mail or the author of the note will receive the e-mail from the trigger.
In your case you want to react to a status update and you want the customer to receive the mail so that’s the better choice for this trigger.
