Zoom for IPad

Hi there,

I run yoga, meditations, and discussions on zoom. I have been trying to play music in the background for weeks with no luck. When I screen share it will not play my any music and when I quit the screen share the music starts. I have tried so many things and am hoping I am missing something. I have tried on my IPhone too and the same thing happens.  I am hoping someone can help because I have about 30-40 people that come and I need to be able to play music. 

Thanks in advance,
