Apple music and audi mmi

Hi! I recently bought an apple subscription so I got all my music on my iphone as icloud music. The point is when I try to listen to this icloud music in my car (using audi mmi bluetooth system or the apple carplay app) it doesnt work. It seems like if the car ( no matter apple carplay or audi mmi) is trying to download All the music of the library and just jumps from one song to another without playing them.

Just the music which is in the decide (not in icloud) is played properly.

Any ideas?

thanks in advance
