Fully working but reduces filtering capabilities, with additional configuration (listed below).
Enable the App: Snapchat web proxy override.
Note that this will also disable HTTPS interception for many other apps that use Google's Appspot platform and significantly reduce the system's ability to filter them.
The Snapchat app does not utilise the device's trusted certificate store and therefore HTTPS interception must be disabled for certain traffic. Furthermore, the app connects to appspot.com but does not provide a server name indication in those HTTPS connections. HTTPS interception must therefore be disabled for both the snapchat.com and appspot.com domains. Disabling HTTPS interception significantly reduces the filtering and auditing capabilities.
