yes, very disappointing. I sent an email and very inconsistent answer with the one I got before:

Your application is in process. We are unable to provide a date when the processing of your application will be complete.
e-Cas is for applications processing within Canada only.

Immigration cases being processed in Visa offices outside Canada use a system different from that used to process similar applications in Canada. As a result, the e-Client Application Status (e-CAS) does not reflect the status of cases being processed in Buffalo.
Do not use the CIC e-Cas on-line change of address system. Your new address will not be downloaded to your file in Buffalo.
