I cant see any messages, or replies!

I am trying to join a game and have been invited to do so as per my email, but no matter what I click on the page never shows any information. It says I have a notificAtion but the only thing showing up is a button that says dismiss all notifications. I can't seem to get to the campaign page or the thread that I was originally using to talk to the dm. I'm getting really frustrated. It's doing the same thing on my phone, google chrome, microsoft edge, and firefox. 

Hi Jamie, Any chance you already accepted the Invite? If so the game will be on your Roll20 Home page or My Games link, doublecheck there, <a href="https://app.roll20.net/campaigns/search/" rel="nofollow">https://app.roll20.net/campaigns/search/</a> Also look in your Private Messages, see if it might show there, <a href="https://app.roll20.net/private_message/inbox/" rel="nofollow">https://app.roll20.net/private_message/inbox/</a> If there's a chance you have another Roll20 account, could it have gone there? Finally, there is the possibility that the GM may have withdrawn, closed or cancelled the game. Last, if nothing helped above, reply here again and we will provide the steps for troubleshooting Bugs & Technical Issues.
