Hi Aeonkryptid,
Thanks for posting here in the community. I understand that you're inquiring about downgrading your Google Home Premium subscription from the Advanced to the Standard plan at the end of a billing month. No worries, help is here!
You can switch from the Advanced plan to the Standard plan of Google Home Premium at the end of the month. The steps depend on where you purchased the subscription. To guide you correctly, could you please confirm where you originally bought it (Google Store, Google Home app, Play Store, or one of our third-party partners)?
In the meantime, refer to this article: Buy & manage a Google Home Premium subscription.
Keep me posted.
Regards,
Melany
