Custom APPS not showing to users

Hi All,

I have a custom model driven App , but this App not visible to user despite following below steps:

• add the new security role to App under 'Manage Roles'
• enabled Read Privilege for Model Driven App Under Customization in security Role

I have user1 and securityRole1, I just copied the role and created SecurityRole2 and assigned this to User2. Both users have same licenses but App is visible to User1 but not visible to user2.

Please guide if I am missing something.

Regards,

Persis
