Many districts use features of Aesop, SmartFindExpress, or SubFinder which make it so some subs will see jobs before others. SubAssistant cannot bypass these restrictions. The jobs SubAssistant notifies you of are the same jobs which you would see if you were logged in to Aesop, SubFinder or SmartFindExpress yourself; SubAssistant will not notify you for jobs for which you are ineligible.
