This is not normal & probably the reason why you’re having issues. You don’t seem to receive state updates via SSE.
Make sure you’re not using any kind of proxy that isn’t compatible with SSE, this includes developer proxies like Fiddler or Charles, privacy oriented tools like Privoxy, or some anti-virus software. Also open the developer tools in the browser and try to figure out why you don’t get updates, there might be errors in there.
