Not sure if anyone is still reading this thread, but I notice the 'watch an ad for Penny fuel' takes two goes before I get a reward.
Graphics disappearing, replaced by bars of colour, after watching ads for free gauntlets/GEMS is also still happening. Means I sort of know what I'm doing when I win an Arena with invisible plants but it isn't much fun.
