Enable private session on Spotify Connect devices

[generous_rose]

Private session mode is not bad. But it needs some tweaking. I can't really use it because it  doesn’t work on my smart devices.

I usually listen to music on my Amazon Echo Dot which currently doesn't have private session. But when I listen to ambient/white noise for sleeping or working, I don't want to listen to it on my phone.

Bluetooth is not an option because I can only connect it to one device, so no multiroom or stereo mode available and seriously the only reason you use Spotify Connect is so you don’t have to use the BT.

It’s becoming really annoying. I wonder why you offer features that only work in a limited way.

Please fix this. This will help a lot of people. Thanks
