If in an automation recipe has been created with a specific person to the task, this should not be overridden by the “When a new item is created, assign creator as person.” Please update the “When a new item is created, assign creator as person” so it does not override other automations.
I have found that when we use the “When a new item is created, assign creator as person” recipe that it overrides any automation that we’ve created where we’ve already included a specific person to the items.
For example we have automations to create pulses for specific tasks everyday and they are assigned to a specific group of people. However, when we added the “When a new item is created, assign creator as person” it overrides the recurring item creation recipe from being assigned to the specific group of people to being assigned to the creator of that particular automation. This means we have to choose which automation is better for our team, when both are valuable.
