Hi Carmen Alu,
Thank you for reaching out. I am sorry that your Google Nest/Home device is not playing your Spotify. I use my Spotify daily so I understand how important this problem is. I appreciate you taking the time to troubleshoot. I would be more than happy to look into this issue with you.
At this moment, this is an emerging issue of Spotify having issues with Google Nest and Home devices. Our team is aware of this situation and are working on getting this issue resolved.
In the meantime, I recommend you casting your music from Spotify.
To cast from a mobile device, you will go to the bottom right of your screen of your Spotify App. You will see a desktop screen and speaker icon next to each other. Once you click on it, it will show which device you are listening to Spotify on. Below that will be a list of devices you can select to transfer your music to. Your speaker should be on the list. This is what I usually do when I use Spotify and haven't had any issues.
I apologize for the inconvenience. Please feel free to reach out with any other questions or concerns. Thanks!
