Why does snapchat not work on my kindle fire hdx?

Snapchat is not officially supported on Kindle Fire HDX devices because they run on a modified version of Android that lacks google Play Services, which many apps, including Snapchat, rely on for functionality. Additionally, the Kindle Fire's hardware may not meet the app's requirements for optimal performance. To use Snapchat, you might consider accessing it through a web browser or using an alternative device that supports the app.
