Marketplace grayed out, X box login stucks on automatic server, No live weather possible

I am still having the same issue and had to submit a Zendesk ticket.
FWIW I found this page - the steps here didn’t work for me but they may help someone else.
I am running a clean install, nothing in the Community folder, no dev mode activated etc.
