How to access state in App getInitialProps

[hqadri2k]

I am using the _app.tsx file to fetch data that is needed by every page on the app. However, at the moment it refetches the data on every page. I want to add a check to see if the data is already in redux, however the store is always empty in the _app file. Is this possible to even do? If not, does anyone know of a suitable alternative?
