Just realized that when I delete a task, the notification pop up disappears on its own in just a few seconds. Why can’t the duplication pop-up work the same way?
I don’t know of a way for turning this feature off in Asana but may I ask why you duplicate tasks so often? If it is because you are creating a lot of the same tasks over and over, you might want to consider creating a project template that you can use to accomplish the same thing without a bunch of pop-ups that you have to close yourself. Asana has pre-made templates you can use or you can create your own custom templates for projects. Here is a guide on how to do that.
We use templates extensively. This time I had a specific project and I needed a section for every entity, and I’ve got 75+ entities. Since we can’t duplicate sections, and my CSV uploader was failing at that moment, I was trying to just do it manually.
The real problem is a pop-up not disappearing on its own, but if it’s not a global issue, then… shrug.
