Samsung R7 speakers / soundbar /TV and Apple Router

I have just bought a new TV, a soundbar and Samsung R7 Speakers. All Samsung Product

I have an Apple Router

I have connected the soundbar and found the speakers.
If I group the speakers the sound is not sync
if I use TV Sound Connect - only ONE of the R7 speakers works.

BUT when I use Spotify - all speakers works perfectly! I can use the volume on all the 3 speakers sepratly. no un synk an it is like it should be.

So what is going on here???? HELP
