Currently using Spotify build 22.214.171.1243 on HTC One M7 on Android 5.0.2 (stock).
I have a NAS running a DLNA server. I use BubbleUPnP and LocalCast apps to watch and to send content to my tv.
Recently these apps no longer finds my DLNA server, and BubbleUPnp opens with this message:
"There was a problem initializing the UPnp service. Try restarting the app after rebooting your device. Check that there is not a background app using UDP port 1900 (used for device discovery), using the 'Netstat Plus' app. Finally, if Spotify is running, force kil it before starting BubbleUPnP."
As you can see in the attachment Spotify is indeed using UDP 1900, and after force closing Spotify, the other apps are working again.
I can't tell what exact version this bug was introduced in, but it can't be more than 2 or 3 weeks ago.
