I control my HomePod with siri 90% of the time and it works about 90% of the time without any issues. I dont know what is going on with people. It sure sucks at answering basic questions but playing music...no trouble.Exactly.
And it’s not like HomePod support is earth shattering. It’s pretty useless to control Apple Music with Siri, there’s no reason Spotify would fare any better.
So it’s seems logical Spotify focuses to support technologies and features that do work.
