Steps to reproduce the problem:
1. Create a new chrome packaged app
2. Upload to store
3. Look for the option "support tab" in the chrome web store

What is the expected behavior?
There used to be an option in the chrome webstore developer dashboard app settings for allowing a "support" tab on the chrome webstore public details page.

What went wrong?
There is no checkbox for enabling/disabling the support tab.

No newly uploaded/created apps can have the support tab.
