After that one tap in the old app, you have full control over all speakers. I'm not at home but that's not how it is now if you're messing with more than one speaker.I guess I may not be following what you're describing. You responded to a comment about controlling volume so I thought that's what you were also referring to. In the old app, if I want to change volume I have to first tap on the mini now playing bar at the bottom of the screen to expose the full now playing screen to get to volume controller. In the new app the volume control (including group control) is embedded in the mini now playing playing bar. So I don't understand how its now more taps to get to volume control.
When opening the app, if my TV is already on and playing through the Playbase, the app doesn't know what is currently playing. It'll usually show the bedroom speaker at the bottom, which is not in use. Then to bring more speakers in and to inform the app that the Playbase is, in fact, currently playing by clicking on the unclicked Playbase, I have to click, click, click, apply, whoops, all sound is gone now.
I'd certainly try to demonstrate the differences but I no longer have access to the old app. If you like the new UI, you're lucky. I'd concede it's slightly prettier, but intuitive? Don't agree.
