This incident has been resolved.

We are continuing to work on a fix for this issue.

Facebook & Instagram are currently experiencing some issues that are reflecting on our integration. For now, adding new Facebook integrations and reconnecting existing Facebook integrations is not available. Moreover, some messages may not be imported (though rest assured, we will import every message missed once the outage is over). You can follow the evolution of the Facebook outage here: https://developers.facebook.com/status/dashboard/
