From the Developer Portal /admin/applications, when developers are allowed to create new applications, the "Create new application" button redirects directly to the inbox (/admin/messages/received) instead of allowing to create the application. 

Attaching HAR where it's visible that /admin/applications/choose_service redirects to /admin/messages?action=new&controller=provider%2Fadmin%2Fapplications&service_id=2555417907918
