If I add new intents to my skill will I have to resubmit for certification, or will simply saving a new build update my bot?
Yes, you have to resubmit your skill for certification.Please use the "Development" version in the developer console below the live skill. The development version has same information as the original live version you can use it to work on your skill and add new features and you can submit this "development version" for certification, both live and development versions remain in your list until the new version is certified. Once the new version is certified, it becomes live and replaces the previous live version.
