If you go to player reviews for the game with your review and click on write a review, it will come up with your review so you can edit it and delete it. Unfortunately, neither options actually work. I tried to edit one of my reviews yesterday, but even though the edit was accepted, the error is still in the review.

Hopefully this will get fixed soon because I really would like to fix the error in my review.

I also experience being logged out when voting however I logged back in and finished voting, and I also experienced the votes resetting however I did vote again twice just to make sure but I do not have the emblems. But I also encountered another problem. There is one category when I voted for the first time, each time I voted it would cause the page to refresh however I skipped but came back to it later and it finally accepted my vote.
