Since yesterday's patch window, all of our playbooks are no longer automatically applying via custom trigger. After some testing, only the 'Alert.' calls have changed. There appears to be no change with 'event.' calls.
[alert.alertname] has to be [Alert.alertname]
This requires a full rework of every playbook we have in production(total 458 playbooks, inactive and active). Some heads up on the change being implemented would've been great!
