Sorry to hear you're experiencing this, as I can imagine it has been an inconvenience. I would love to look into this further for you. Have you had the chance to check out this article going over the process of connecting your devices to Alexa? If not, you should definitely check it out and let me know if you still need assistance.
As Alexa is not a Google or Nest made product/service, it is not a guarantee that all devices can be connected to the Google Home app or link with your Nest products. Sorry to hear you are unable to connect the two products together. Please share your feedback in the app.
@bdeflaviis I wanted to follow up and see if you are still in need of any help. Please let me know if you are still having any concerns or questions from here, as I would be happy to take a closer look and assist you further.
I appreciate your help, Brad.
We understand that you're still having problems connecting your Nest doorbell to your Alexa speaker. I found an article that might help you with this issue. In case the steps did not work, you might want to contact Alexa support team and ask for assistance.
