Lost a game before it began.
I am having the exact same problem. Instant resignation (loss) when someone offers a rematch. It's not likely the player. Seems to be an error. Not sure how many are affected. I recommend not taking any rematches till it's been fixed. Sucks though I love rematches. As for the previous responder. Why bother coming to the help and support forum if you offer neither help nor support. It's you that needs to move on...
