share m4a file via whatsapp

[gcoria]

I'm trying to share an audio file(.m4a) with shareViaWhatsApp, in android works without any problem but in IOS doesn't, i added whatsapp to the Whitelist so that's not the problem, when i try to share the plugin ask me for a title but then only shares this title without the audio file, the path to the file it's also ok because it's the same that uses to play the audio

The problem has something to do with the format(.m4a)?
