I often have trouble choosing some of my Sonos speakers
when I connect to new device/sound source in my Spotify app.
I have Spotify Premium
They are gray-colored. See attached picture.
This problem I never have via my Ipad or
Macbook. If it's gray in my Iphone and I choose to start the music via my Ipad
Then the devices will not be grayed out anymore when the music starts and I can choose new audio source via my Iphone if I want to.
This problem happens regularly but not every time I listen to music,
Everything is connected to the same wifi network.
My Iphone is an Iphone 8 with latest iOS and latest version of Sonos
and the speakers also have the latest update.
My Ipad Pro has the latest iOS and latest version of Sonos
Grateful for help
