Hi Jenk, It sound like your NEST AWARE is not activated. You can check it like this...
Go into the GOOGLE HOME app at the very top level (where you see all your devices). Click on the Settings (Circle with the gear icon). There you will see under 'features' NEST AWARE. Click that and see what it says.
Good luck and let me know if that helps.
(keep in mind your old recordings will not be there after you active NEST AWARE. Only new stuff will be recorded)
