I created an Azure Storage Sync Service and an associated sync group yesterday to test something. I have never registered any server endpoints or setup any cloud endpoints on this sync group. Today I tried to delete the sync group, and I'm getting an error message that says "before you can delete this sync group, first delete all server endpoints, then delete the cloud endpoint". My "registered servers" tab says "no items to display". Does anyone have any idea as to how I'd go about deleting this sync group and the associated storage sync service?
