I see this is still an issue.  Another vote here to remove the requirement than the ticket status be OPEN before the due date can be changed.  Silly.

Agreed.  Having the same problem here.  Need this enabled.

Agree, just ran into this problem. Seems unneccesary hurdle from enduser perspective.

Is there an update on this. It makes no sense whatsoever

We have never needed this, but this is a dumb restriction and I can see the need for it.

+1 for this as well.

The issue remains the same 4 years after it was raised here! Come on Freshservice! Not only do you have to change the status to Open to change the due date but when you change the status from Open to something else, the system changes the due date back to what it was before it was updated. Argh!

Would like to add my support to getting this changed.

This tends to throw off our reports.

This would be a nice feature to have a quick option to change without opening a ticket.
