Thanks for posting on our Canny boards!
I see that this post was made in March 3rd, and we've done some improvements to our Automations in between!
Can you confirm that "When task is unblocked, assign to xxx and change due date to xxx" is still not working?
If so, can you write into email@example.com
so we can ask for login permissions and do some testing?
Let me know if you have any more questions!
