I know similar questions have been asked a while ago, but without an answer.
I have an Alexa enables Sonos 1 in the lounge and a Sonos Play 1 in the kitchen. If I say ‘Alexa, play music in Kitchen and Lounge’ it works (I created a group on the Alexa app).
The Sonos app shows Kitchen Lounge ‘Started from amazon alexa’. However, if I go into the kitchen where the Play 1 is with no Alexa voice assistant, I can not stop, pause etc the music using the physical buttons on the Play 1, or on the Sonos App.
I assumed you could control any Sonos speaker using the buttons or the Sonos app, regardless of whether you started the music by Alexa, buttons or App.

Have you set-up the Preferred Speakers within the Alexa Group? (Please see my post: https://en.community.sonos.com/amazon-alexa-and-sonos-229102/an-overview-and-explanation-of-the-new-support-for-alexa-grouping-6817788) The Sonos system is designed to work with any combination of the following: Initiate via Google, stop via the app or physical buttons, and restart via Alexa.
