Google reportedly ending legacy Nest Aware subscriptions for some users
At least one UK user has received notice

Google offers a subscription service to go along with its Nest cameras called Nest Aware. In May of 2020, Google overhauled Nest Aware's pricing model, which now starts at $6 per month, no matter how many cameras you have in your setup. Google stopped accepting new sign-ups for the older Nest Aware plan when it rolled out the new version, and now, it's apparently canceling legacy plans for some users.
