Issue with Custom Domain Verification - Automatic Addition of Root Domain to Organization

I'm encountering a persistent issue with adding and verifying a custom subdomain in my Appwrite project, and I believe it may be related to an unexpected behavior where the root domain is automatically added to my organization's domains. I've followed the documentation and community advice closely, but verification continues to fail. I'd greatly appreciate your assistance in resolving this.
I'm happy to provide more details, screenshots, or access if needed.
