Hi Amplitude Community!
It is the case that Amplitude does not auto track crashed sessions or events. However, if you're able to instrument an event that is logged when your app crashes, you can certainly send that data to Amplitude as well, either via our SDKs or via HTTP API.
See available SDKs here: https://www.docs.developers.amplitude.com/data/sdks/
If you have a best practice for tracking crashed sessions or events and sending to Amplitude, you are more than welcome to share your thoughts in this thread!
