There are problems with UI for external integrations since the recent changes to story layout:
* On existing stories that had an external integration ID before the change, I can see the external ID, but there's no way to edit it.
* On new stories or stories that did not previously have an external ID, there's no way to enter it.
Pretty unhappy on both counts. :(
You're right about the integration ID field. We introduced a bug in the update which is preventing it from being displayed for you (and others). We consider this to be a serious regression, and hope to have a fix for it in the within a couple of days. We will keep you updated,
Sincere apologies for the inconvenience and frustration meanwhile.
