the Oncall workflows are controlled by trigger rules. we have a trigger rule for when an assignment group is null. When the incident is assigned it no longer meets this criteria and is looking for a rule that matches the assignment group. This is working as expected and trigger paging (we are using twilio for paging)
However, If we create a rule for when assignment group is not equal to null or we add assignment group in the trigger rule it does not trigger paging if incident created with assignment group
