No Volume control with iPhone X, chromecast, iOS11

[Nox79]

Impossible to control volume throught my chromecast, with my iPhone X and iOS11.2 (15C5097d)

It was available with iOS 11 & iPhone 7 Plus.

Same issue here with Alexa Echo Dot

I’ve found solution

open spotify 

connect to chromecast

and control volume directly with Google Home Application

I thought the same thing with me. If I’m using Spotify to play through Sonos, I cannot control the volume through Spotify, only Sonos. I used to be able to control the volume whether the phone was open or locked but now I have lost that ability

It works with iOS11.2 beta 15C5107a & Spotify 8.4.27.

I can control my Chromecast volume directly on Spotify
