My Nest App has a Nest Thermostat and several Nest protects I recently added to it after not using it for a long time.
I now also have a Google Home app with several things on it including Google Mesh.
However, when I try to migrate my Nest App account using the "Migrate to Google Account" it say "Google Account is already linked with another Nest account". Which I may have created accidentally at some point during the setup. It's empty though.
Is there any way to de-link the empty account and move over the Nest account that already has everything set up on it?
I'm sorry for the delay. It is not possible to unlink a Google Account and Nest Account that have already been linked to each other. Fore more info and detailed steps, check this article on FAQs about accounts for the Nest app.
