spotify connect problem

[1170198450]

Hi!

I'm having really annoying problem concerning spotify connect. My Ipad is connected to speakers. I am not able to control volume via my iphone or macbook. It is greyed out. When an album is finished i am not even able to play next one without using an Ipad. It says 'you can't use this device' or 'this device is not available' on my iphone or macbook when trying to connect to an Ipad. And it is greyed out as well.

Before PC with Windows was connected to speakers and everything worked properly. I was able to control everything via my iphone, ipad or macbook. 

Why does it stop working? It is really annoying. I am Premium member by the way.

Cheers!
