We have created a new App having few Custom objects (with associated Tabs) and few Standard Tabs (Opportunity, Product etc.), now when we package this App and install this to another account, we are expecting to display all required Tabs by default i.e. user shouldn't be required to customize the Tabs and turn on the desired Tabs.
The Problem is, all the Custom Tabs are displayed at the target account except the Standard Tabs.
How we can do this?
