Only on IOS, embed only shows preview: "the token provided isn't working."

Hi all! First of all I want to thank you for the cool API. I've developed a little app that loads tracks in an embedded player. It works great on my macbook pro chrome browser. The authentication flow triggers, and I'm able to load tracks in the embed as a premium user, no restrictions.

On the ipad and iphone, all works great until I load a track. All of the tracks load in preview mode, even when I'm logged in. 

I see this in the IOS console on both chrome and safari whenever I try to load a track:

the token provided isn't working.

followed by

created authenticated browser transport

In the screenshot below I'm grabbing a track and then trying to call loadUri on the enbedController. It works great on my laptop, but is behaving on IOS like I'm not a premium user. Any ideas?

This is an expected behavior if you're using a mobile device. Keep in mind that full playback is currently available just on the desktop web when authenticated (ideally using Google Chrome). [Source: a comment by a Spotify employee]
