We are investigating event triggers not working and also not visible in UI in AWS US stack (https://connection.keboola.com). No flows based on event triggers are being executed at the moment. Time based schedules are working as expected as well as event triggers in other stacks.
Update 13:35 UTC: We identified the root cause and will now proceed to restore event triggers configurations.
(Resolved) Update 14:05 UTC: We restored event triggers configurations, all event triggers are now working as expected and we don't observe any failures regarding even triggered flows. However if you still experience issues please contact us on support to resolve it further.
