-<!-- Yes or No -->
-2. Did you checked [compatibility notes](https://github.com/piotrwitek/typesafe-actions#compatibility-notes)?
-<!-- Yes or No -->

+## How to Reproduce
+
+<!-- You have two options, fill in a codesandbox template or provide full working code example. -->
 
-**CodeSandbox to help you reproduce issue in isolation**
+### CodeSandbox Link
+<!--
+Codesandbox will speed response time and your issue will be prioritized because it's easier to analyze:
 https://codesandbox.io/s/github/piotrwitek/typesafe-actions/tree/master/codesandbox
+-->
+*(PASTE HERE your codesandbox link)*
 
-<!-- If no codesandbox, then please provide a full working code example including actions, reducers and all necessary types so an example is complete. Code snippets out of context are not enough and your issue will not be valid. -->
+### No CodeSandbox Link
+If no codesandbox, then please provide a full working code example below including actions, reducers and your custom types used in the example.
+<!-- Code snippets are not enough because they are out of context, to analyze your case we need a full working example. -->
+```ts
+// PASTE HERE your full working code example
