I'm part of the System Administrator role/profile. I created a custom object and added some data to it. Other system admins created data as well. When creating the object, we assign ourselves as the Owner of that record. We cannot see each others data. Why would this be?
Note: Sharing is allowed for the object. Under Security Controls -> Sharing Settings, Default Extranet and Intranet access is Public Read/Write, and Grant Access Using Hierarchies is checked. There are no existing sharing rules for the object.
Note: One thing to mention is that these custom objects have "private" attachments attached.
Update: The issue is not security related, rather it seems that I was only viewing recent records. I was tricked by this, since the view name selected was 'All' -_-
