@ammont82 the i9n tests failed, here's the failing test. Reason: TypeError: win.__app__.OCM.setAuthInterceptor is not a function. This is due to the refactor made in /ui-lib/lib/ocm/index.ts. In order to fix that the code should access the setAuthInterceptor function from OCM.Api, like this: win.__app__.OCM.Api.setAuthInterceptor.
