If that does not work, please e-mail firstname.lastname@example.org. Related articles I downloaded the Tapingo RX app but can’t log in. I need the link to download the Tapingo RX app again. Where can I find it? Who is my campus manager? It says “Untrusted Developer” when I try to open the Tapingo RX app on my iPhone. How does the schedule work?
