Shame to hear yours isn't working well, mine works pretty much perfectly so I am sure it's capable of working fine.
I am also using a local account to signin to Windows, but it works just fine if I sign into the Xbox app using my hotmail account.
Are you running any apps that might interfere with it? can you try closing stuff down to see if it fixes the problem.
Are you running anything on your network that might be killing it? i.e. pihole traffic blocking or a physical firewall?
Have you ever run anything to rip features out of Windows or to try and streamline it?
Not using any apps that I know of, the XBox app is the first app I've installed.
Not running anything on my network that would block it and only using Windows firewall.
Not streamlined anything, standard W10 Pro install patched and up to date (1903). I usually rip loads of stuff out but I couldn't be bothered on my last install.
I've just installed another game via the MS Website and it has installed ok. However, there is no folder for the game on that partition apart from a couple of folders that are empty, strange.
