When will I see my monthly discount appear on my Account for the (Federal) Advantage T-Mobile Program?

A few days ago I received the confirmation email for the Advantage Program:

I should be receiving the federal discount of 15% each month, but my account doesn't mention it anywhere.  When will this populate?
