XCRC not working?

CRC checking is enabled though it doesn't automatically check after each file download.
Tried disabling, then re-enabling, setting to different file size limits, but nothing...

Though I can send the FTP the raw XCRC command and get a correct response.

Tried using a multitude of FTP servers on the other end and each the same thing.
Anyone have a clue on how to enable it so it works automatically?

If this is any consolation, running connection with Implicit SSL (Explicit wont work... grr at the end-user router)

Use the global queue for your transfers. If the server doesnt support XCRC it wont work.
