Hello there!
Please remove NETLIFY records from our app (we are aware of the website going down afterward).
The app: relaxed-roentgen-b3dad7.netlify.app
The domain: getoyama.com www.getoyama.com
The error: This is a system record that cannot be managed directly.
Also, these records persist even after removing the domain linkage to the app itself and due to this we cannot define our new A records (error: 400 - link exists, all config must be empty).
Best regards!
