Too many ads. Whenever I get a rare character I watch the ad but it doesn't let me see my character, and so I have to watch another ad because of this glitch. Sometimes I watch like 10 ads until it finally works. Fix this glitch because it is too irritating and I feel like we are being played by the developers just to watch more ads so they can get more money. And from I've seen in other reviews, I could buy the potion is useless because the game still glitches and makes you watch ad after ad.
