When playing a song using the Web Playback SDK (initializing a new device and then sending a play command through the Web API), the playback progress (ie. position) is not reflected on other apps or in the /v1/me/player/ endpoint. The value is stuck on whatever is sent on the initial play request, and only updates when using the .seek() method (which of course interrupts playback for the user). This occurs on any browser.
Here is another topic referencing what seems to be the same issue. https://community.spotify.com/t5/Spotify-for-Developers/currently-playing-returning-incorrect-progre...
For me it doesn't stay at 0. It stays at the position it was last paused at. So there is no playback position update sent from the webapp as it seems.
It seems that the problem has been resolved, at least for me.
Thanks for updating the thread @Straightea.
@sigloasesino are you seeing that the issue has resolved for your app too?
