Play() methods plays from the beginning and doesn't work after play and SeekTo issue

I have this code:

private async void Play(fileUri) {
     // e.g., fileUri = "http://somesite.com/someaudio.mp3";
     await CrossMediaManager.Current.Play(fileUri);
}

And always I play the audio, it loads the audio through HTTP all again and plays from beginning. What’s the right way to handle the player?

Also, I have this:

private async void Pause(object obj) {
     await CrossMediaManager.Current.Pause();
}

If I play a sound, pause it and play it again, it plays like a second and stops, I don’t know the reason.

I’m honestly not sure. As I said, my only experience is with seeking while the media is already playing. Maybe someone else knows.

Here’s what I do:

When starting a song for the first time:

IMediaFile mediaFile = new MediaFile { Type = MediaFileType.Audio, Url = mediaSource };
await CrossMediaManager.Current.Play(mediaFile);

Pause:

CrossMediaManager.Current.Pause();

Resume:

await CrossMediaManager.Current.PlaybackController.Play();
