Atlanta Public Schools (APS)

I'm not sure if this is an app problem or an APS problem, but multiple times this year I have received a message stating that my child's bus number has temporarily changed and I need to look for a different bus. The issue is that I receive this message about 20 minutes AFTER my child gets on the bus. Again, I don't know if the app is delayed in sending the message or APS doesn't issue the statement until the I information is irrelevant.
