Not receiving invites

I have been invited to join a game via 'Find a Group' (invite definitely says pending for GM) but I'm not getting anything. Not sure what to do, any ideas? Thanks very much!

Get in contact with the GM and have him cancel the invite first then you can post to the campaign's looking for player page (it is the page you see in the game listings) and have the GM click on the invite button that way. If that is the way you are having problems with, the GM can copy paste the invite link into a pm and send it to you. Those are the two recommend ways to get a valid invite.
