Did you recently migrate to the Google login? Let's see if we can use the Google home app to fix this:
Open the Google Home app.
Select the home structure that you want to apply the hanging subscription on.
Note: Make sure the you're signed in with the account you used to purchase the subscription. Select the account profile icon, then select the correct account.
Tap Add Nest Aware under Manage Services. Alternatively, tap Settings > Nest Aware under Features.
Tap Apply to apply the hanging subscription to the home structure.
After applying the hanging subscription, you will be taken to the Nest Aware setup screens where you can finish setting up Nest Aware features.
