'getFIles' does not fire after audio record

[anki247]

Describe the bug
The event getFIles does not fire after recording audio. Even cancel event fires sometimes (mostly not). From 30 tries I saw once that getFiles triggered with correct data which seem for me weird...
I also see that the recorded audio is saved in [Appfolder]/IQAudio, but if there is no event I can not detect when I can look into this folder... :(

To Reproduce

• open app on real Device (for me it was iPad)
• call openAudioPicker with isCaptureMood: true
• record audio
• Done -> no event gets fired...

Expected behavior
getFiles triggers with file info

  }
};

export const pickMusic = () => {
  let mediaPicker = new Mediafilepicker();
  mediaPicker.openAudioPicker(audioOption);

  mediaPicker.on("getFiles", function (res) {
    console.log('--> FILE ******************', res);
  });

  mediaPicker.on("error", function (res) {
    console.log('--> Error: ', res);
  });

  mediaPicker.on("cancel", function (res) {
    let msg = res.object.get('msg');
    console.log('--> Cancel: ' , res);
  });
}
