I have 200 coins that I got through one post. I can't figure out how to use them though. When I click on the "Give Award" link in a comment, a screen flashes up and I'm immediately taken back to the post in question. I think it's supposed to be the screen to choose which award but I can't be sure because it just flashes there for a second.
Also, I can't use anything else related to Reddit Premium -- when I go to the page about it, none of the links work. This is true on two different accounts where I have received Gold.
