I don't mind the ads because I know developers have to make money some way, what really irks me when I try to press the watch ad button so I can get my "free" item, it doesn't work until I exit out the item. Then the ad comes on immediately after I exit out, so I watch the ad but I don't get my free item. I slightly more forgiving but this has happened to me ever single time. It doesn't matter if I turn the game off, at the shop, or just leveled up
