players are not connected, can play different streams simultaneously, many

[ljo002]

Spotify family, about 16-20 players (including some google Home groups ), mostly google cast, 2 Bose portable players, onkyo, sony, Denon recievers, controlled mostly by apple watch/iphone, ipads, google nest, google home. Spotify connect often not connected to all players, can often play different streams at the same time. Sometimes it all works, sometimes not. often endless "connecting..." even after restart of spotify. Semms lika a IOS and Google side of things depending on which device the music was first started on. Right now music is playing on the Boses that I started in the google nest in the kitchen, but I can play different music in the study on my Arcam system from my apple watch?
