I carefully followed the instructions outlined here to build my customized Moodle mobile app:
After editing the config file and running gulp, I did a test with ionic serve where the app worked perfectly fine in the browser. On Phonegap I am able to compile the app using my development key, however when I open the app on the iPhone, I only see a blank/white screen after the splash screen. I re-compiled the app from scratch on Windows and Linux multiple times without success, so I am out of ideas.
During the build process I ran into the issue tracked below, updating to npm V4.2.0 solved the build issue:
Any ideas what could be causing the blank screen on the iPhone? Thank you for your help!
