I actually do not understand what happen when user hits thr reload page on the web browser ...

Getting user data displayed after login on first pass is OK... store.state data are available ( so are localStorage caching data) But if I reload the page the even if store.sate data are available they are NOT displayed anymore ..

see the console.log

=== starts displaying home page ===================

console.log
