ADK - If you're requesting your sites by period your withholding amount should be visible. If you are clicking by date range, it is not.
I didn't test yesterday but today it's the way it always was and that's how you'll see the amount being withheld.

GeorgeTH - Scroll down a little - below the box where the link codes are, you'll notice a link that says 'Click here to download a file of linking codes for all sites' - this is available for all linking codes.
