Spotify Version:220.127.116.11.ge6957e14 (issue was also present in the last few builds)
After locking Windows and unlocking computer it is not possible to resume playing track, nor play another track. Closing program via menu or X button does not cause process to terminate normally. Trying to launch Spotify again - "Spotify is not responding" message.
Start playing track, pause it
Lock Windows with Win+L shortcut or let the system to be automatically locked after a period of inactivity
It's not possible to resume playing track
Kill Spotify process in Task Manager, start program again.
I did not have these issues on the same machine under Windows 8.1 Pro. Issue encountered after upgrade to Windows 10. I have reinstalled Spotify, same behaviour.
It seems we never received a reply. We'll set this as "Closed" in the meantime.
Feel free to give us a shout if the issue persists.
