Can the admin team member re-sync or disconnect the Meta and Google profiles on my account?
Yes, if you allow it. A member with the Admin role and the Connect Meta (or Connect Google) permission opens Connect Meta or Connect Google and sees the same screen you do: re-sync, connect another profile, rename, choose the primary one, remove, disconnect, and manage accounts. Everything affects YOUR account.
Members who are not Admin, even with the permission, only see the profiles already connected and the Connect profile button. The profile they connect goes into your account and appears to them as Connected by you.
The Collaborator role doesn't include Team, Connect Meta, or Connect Google: when you choose Collaborator, those boxes disappear and stay unchecked. My Subscription remains with the owner only.
