I have built an API app using the iTunes API with my students from the following tutorial: https://docs.google.com/presentation/d/1xplE4PEc2LImvFApVplOuumtGFOuikfI6y5lA9uDwmk/edit#slide=id.g9b2342e0f_0_28
It works fine on Android, but on iOS instead of playing the mp3 clip, we get an error of:
Runtime Error
undefined variable. Irritants: (yail/yail-dictionary)
Note: You will not see another error reported for 5 seconds.
Based on another help message, I did make sure the phone is not on silent mode. But the error message still appears.
Here is a link to the app in the Gallery: MIT App Inventor Gallery
