I just built my first react-native app through expo and published it for the client to view. They can click the link on their android (where they downloaded expo client) and it opens and runs fine. WHen they click it on their iPhone (also downloaded expo iOS app) it opens expo and then returns a message that it can' load and to go back to the expo home page basically.
I've built this app specifically with iOS and android in mind and I thought that expo handles that for both published testing and deployment to the app stores, however, I don't want to have to pay the iOS 99 dollar fee yet just to let them test this on an iPhone.
Does anyone know why a successfully published app that opens on android through expo won't open on iOS devices?
