I also have the same issue. I saw on Twitter that some people are having this issue specifically when they're done with the quests, but for me, there was no way I was finished, as I've only played 9 matches today-- one was a loss, and they were mostly in the Premier Draft as well. I don't think I've gotten the rewards after, as I ran another match once the draft was over and nothing came up to tell me I got a card or any such thing.
