Same here, no longer working.
Big disappointment, Sonos

@Emil thank you! I can confirm it is fixed.

Can anyone confirm this?
I am using Sonos S2 on multiple Play:1. the provider detects the speakers, however does not control them anymore, e.g. volume control, play/pause. Neither on flic button nor on the twist.

On Nov 16, Sonos rolled out their software 15.10.
since then, the flic Sonos integration no longer works for me on my hub (both flic button and twist).
Anyone else encountered this? Any eta when this will be fixed? Thanks.
