Thanks for posting.
This is not the experience that we wanted you to have, let me help you out. A few things: which Nest camera? Is your camera in the Google Home app or Nest app? Are you signed into the app? Did you receive email notifications? Were there any recent changes made before the issue started?
Make sure your phone or tablet’s settings aren’t blocking notifications from the Nest app. The links below will take you to Apple’s and Google’s support websites.
