I have a 3 step approval process set up. Today I noticed that there were a few tickets that were pending. When I looked at the tickets individually the first CAB had voted yes to approve (that CAB requires yes votes from both members before it goes to the next step). It didn't go to the next step in the approval process. I had to manually override that first step before it would go to the next CAB. The rest of the approval process went smoothly, the action rules triggered the tasks appropriately once the tickets were approved on the other two steps.
Has anyone else seen this or know why it would have stopped on that approval step?
