After the 16.1.1 upgrade, the create new Button (+) is missing in the Risk page.
The button was missing for all users including the super user admins as well.
The below steps were performed but the issue persist

--> Flushed caches
--> Deleted all custom views from the Risk page
Release : 16.1.1
Removed the Risk section from the Blueprint page, published the Blueprint and then added it back and published again and that fixed the problem.
