I have raised a support ticket about this, but thought I would reach out here to see if I can get any good suggestions in the meantime.
I created and registered a Model Signing Key to a store Brand Account that I wish to revoke or disable somehow. After a bit of googling, it doesn’t seem like it’s currently possible via standard user tools and API.
Here are some related posts on this forum:
Has any progress been made ? Can I just register a revoked version of the key [ after doing a gpg revoke operation in
gpg --homedir .snap/gnupg/ ] ?
