I downloaded the app as soon as it was available & it worked fine. Now several weeks later, I can rarely get the app to open. It flashes momentarily then immediately closes. I’ve tried to delete & reinstall numerous times. Twice when I was able to register my child again, I received a notice that no bus was assigned. There is no option to request assistance, notify the developer of a problem or contact anyone. If I could submit this with zero stars, that’s exactly what I would do.
