I have got hot reloading to work fine on my Mac, I think (although it seems I still need to refresh the page?).
But on my Windows it doesn't even work after I reload it.
On my Mac in the DevTools console I noticed these 2 lines:
[HMR] Waiting for update signal from WDS... [WDS] Hot Module Replacement enabled.
Which doesn't appear on my Windows, so I suspect there's a problem about there?
npm run hot just tells me it's set up fine.
I'm using Windows 10 and Chrome 65 or something (newest)
