A few days ago, an app allowing Amazon Prime Instant Video content to be mirrored to Chromecast arrived in the Play Store. Primecast is now nonexistent after thirty-six hours of service. The app was pulled from Google Play. We assume Amazon stepped forward with some legal formalities that prevented Primecast from remaining in service.
The developer, at this time, is unsure whether or not Primecast will return to the Play Store. We wouldn’t count on it. At the very least, we can hope that Amazon sees there is a demand for its content to have Chromecast support.
