I've created a custom object "package" in sandbox and deployed it to production.
I can create a record for "package" from record detail page. But object is not available on Tab. even When i Click on "Plus" icon, then also "package" object is not visible.
I'm a System Admin. I've checked the profile for system admin. Under Tab setting, I'm not able to see my custom object. But that object visible in the "Custom Object Permissions" for same profile.
