Disabling chrome extension or removing composeWithDevTool from your code will work as a quick fix. But we all know that we need the extension in order to track our application state and manage it properly. So I created an issue today please support hopefully, someone from the redux team will get back to us.

Or if you are looking for a temporary workaround(for chrome), you can download https://github.com/zalmoxisus/redux-devtools-extension/releases/download/2.15.5/extension.zip and then extract it to some folder.

Type chrome://extensions and turn on developer mode from top left and then click on Load Unpacked and select the extracted folder for use.
