I had a deadline for my teammates to submit their entries by a certain date and time.
Once I deactivated the form, you see this message from Asana:
When a form is turned off, the customer or teammate sees a custom message that is kinder and more clear. Similar to how you can set a custom message after the form is submitted, I would like to be able to set a custom message once the form is deactivated. For example, “This form isn’t accepting responses right now. Please contact Jim Smith for assistance.”
Also, I made a task to myself to deactivate the form when it had expired., but it would be nice if that was automated as well ( just saying).
