Hi ​@J123456,

After checking with a colleague (as I don’t have an iPhone to Advanced Trueplay with), the ability to toggle Trueplay on and off is available in the app. If you’re not seeing it, then either the app isn’t full up to date or your speakers don’t have an Advanced Trueplay configuration on them. 

If your Sonos App is up to date and the option isn’t showing, then check with an iOS device to see if you need to configure Trueplay again. If the iOS device shows that Trueplay is configured, then try and reset the Sonos App on the Android device by going to the Account icon in the top right of the app → App Preferences → Reset App.

I hope this helps!

Are you looking in the right place for the toggle? It should be there under:

Settings - Room/Speaker] - scroll down to Trueplay, under Sound - then toggle on/off. 

I see it on my iPhone but its definitely not there on my Android phone (s25 ultra) already done a reset and that and everything up to date. It's never been there in the new app.

For some reason this screenshot was messing in my last message
