Submitted CommonApp/Supps to 2 schools at once, but only got confirm. email for 1?

<p>I submitted my Common App and supplements for two different universities. CommonApp then sent me an email confirming that I had successfully submitted my CommonApp for College A. It sent me another email confirming that I successfully submitted my supplement for College A. However, it didn't send me anything for College B, although on the Common App it says both the app and the supplements have been submitted for College B. Is this a problem?</p>
