Breakout by app version

This is an optional way to get alerted, by toggling the "Send an alert for every app" you will get alerted for every app version that has its crash-free sessions rate drop below the threshold.

Conditions

You have 2 conditions you can choose from:

App version

You can select "Top Releases" or "Latest Releases", or specify app versions

🚧

Controlling the noise if you have many app versions

It is recommended to specify intended App Versions to be alerted about when checking "Send an alert for every app version", otherwise if you have many app versions released, it might get too noisy.

Session count

You can specify "Greater than" or "Less than" to specify a number of sessions to be able to reduce the noise

Forward Alert

Then you can set the option to forward the alert to your favorite integrated tool.
