I previously used Google Workspace purchased monthly through Squarespace. I canceled both Squarespace and Workspace and maintain my domain for other uses.
I see no way to permanently remove this primary and only domain from Workspace. This is interfering with other uses including continued use on my Android phone, the purchase of YouTube Premium and Google Fi. An error results stating that an admin (that's me) has locked out the option to purchase Fi or YouTube Premium and on my phone I am unable to do reviews of apps but works otherwise. Occasionally I get errors when using the account and just switch to a Gmail account.
How do I remove my domain which was never registered through Google Domains but did use DNS?
