i created 2 Groups "Site Owners" ( with Approve & Contribute Permission) and "Site Member" (only Contribute Permission ) and i have 3 account (Administrator, Useradmin ,UserMember ). "Site Owners" has Administrator, Useradmin while "Site Member" has only UserMember but Owner of "Site Member" is Useradmin instead of Administrator. i changed Read & Edit access to "Only their own" in List Advanced Settings also i configured "Permissions for this List".
When UserMember Creates new item , Useradmin can not see any Item but administrator can see it. Why ? Isn't Useradmin is Owner of Site Member ?
