Are you signing onto the Google Nest app using the "Sign in with Google" option using the same Google Account and the same Google Nest "home/structure" you are using for the Google Home app?
You might want to contact Support for assistance in getting all of your cameras in the same Google Nest "home/structure" on the same Google Account:
1. Go to https://support.google.com/googlenest/gethelp.
2. Select a category/product family, and type in a brief description of the issue, then click "Next".
3. Select your device from the dropdown, click "Other", then click "Next step".
4. Under "Resources", just click "Next step". (Clicking one of the listed links will bring up a Help page.)
5. Under "Contact options", choose to get a phone call or chat with the team, depending on availability in your country.
Most Google Nest customers have only one Google Nest "home/structure". The name shows on the initial screen in both apps. If you have more than one, there is a drop-down menu that lets you select one.
