I've implemented UAirship remote notifications a long time ago and everything works perfectly. Recently I tried to add a custom notification sound, the file follow Apple rules:
- Linear PCM 16 bits big-endian signed integer, 2 channels, 44100 Hz.
I'm sure the file is correctly attached to my project because it worked with local notifications, and if a see the file properties I can see that the target was set, and if I check the Project > Build Phases > Copy Bundle Resources, the file is there.
Before releasing my app, I tested this using the PHP Framework to send a push and it worked, but now on production it doesn't seems to work.
Could this be a UAirship bug or Am I missing something here?
BTW: The custom sound isn't playing but the notification is arriving with the default sound.
I hope someone can help me.
