After I grow a plant, when it gives the option of double reward by watching a video, I click on double reward. And it shows a video which I watch also, after that the screen goes black, nothing happens, and I had to close it, when I try to open again ,it says forest app is not responding.And when I click OK for that, and open the app, it opens, but with only half reward, there is no double reward given , even after I watch the advertisement video, what kind of cheating is this? Please fix it.
