I beat the Sunstone Dragon in the current Battle Arena tourney and didn't get the 5 gold or 2 Xmas presents. I'm also getting continual ads for new games and it looks like the game is constantly "resetting" and synching. Seems to be happening every 5 minutes or so the last couple days. There are about 5 or 6 quests to download new games... I have a feeling that may have something to do with it. Usually there is only one new game quest to download and play... maybe the code is going to overdrive with this many quests for new games.
The dragon I used to beat the Sunstone is not healable and the Battle Arena is on cooldown so it looks like the game recognized the win over the Sunstone but I just didn't get the gold or presents.
Resetting the device has not helped.
