We have received confirmation from Twitter that as of 2:26pm PT on August 5th Twitter has relaunched the MACT API. You should now be able to see conversion data in your third party Mobile Measurement Partners (MMPs) dashboards. Any campaigns that are running will continue to deliver as expected and are just as effective as they have been in the past.
