Been playing for a couple of months, now on level 300. Quite a few pop ups when you first sign in but then you're free to play, until 3 days ago! Now videos pop up every couple of minutes some 30+ seconds long mid spin. On a free app I don't mind the option to watch video ads for free rewards out of choice but now videos pop up when you log in, when you win, mid game, in a feature. I will delete the app if these don't disappear. Very annoying. Never had a problem before this week!
