As the title states, even if I'm already signed into robertsspaceindustries.com. Although I did find a wonky workaround (thanks to @Dorathaadestroya ) - use your browsers incognito mode. You'll have to sign in, but at least the community hub page will actually bring up the sign in page and let you sign in! Brave browser (chromium based) v1.47.186 (cookies accepted and shields lowered doesn't help)
