jrwork is correct regarding an MoC call. Typically, USAFA will reach out to the MoC that is being charged with that candidate a few days prior to the portal change so the MoC can personally contact the candidate.
A thing you need to realize is that although you could be on every MoC slate, it doesn't mean you will be charged to that MoC. Nor does it mean that if you are charged to the MoC they will reach out to you.
~ Look at where you sent your request for a nom. For example, our DS sent all of his request/application to their office in our state, not to the DC office. If the office in your home state does not relay it in a timely fashion, and if the MoC is busy voting on bills, than they may not reach out to you.
So don't look into this as anything more than this was the MoCs way regarding appointments.
