OK, so this is Valve and to be expected. Since the game actually went live the servers have already gone down so the game is not stable as of writing.
It appears that the server problems are having a knock-on effect when it comes to receiving anything after the tutorial. For now, just keep checking and maybe Valve will get themselves sorted out and fix the servers. Packs are appearing for folk after a period of time which indicated there’s just a problem at the Valve’s server side.
