Anyone know why the Spotify Web Playback SDK isn't supported on mobile? The docs [1] say "It’s the same technology we use to power our Web Player experience", which seems to work fine on my mobile browsers. However, mobile browsers are explicitly listed as unsupported. The docs also clarify it's powered by Encrypted Media Extensions, which is supported natively back to iOS11 and Chrome 42 [2]. There's also an actively maintained polyfill [3].
