I have sumitted a card which has been accepted and has been listed and has gone live.
In the preparation of this card, I followed the prompts and uploaded a music file which I made myself of me playing the violin.
It is a .wav file and has a Bit rate of 176 kbps and a file size of 869 KB
When I preview the card, the music plays. However, it seems that the people to whom I have sent the card see the picture but do not hear the music.
What am I doing wrong please?
