Has anyone else had problems when going into there underground app with other apps advertising. Everytime i look at some MMA news in my App it directs me to my app store advertising a new game. IM OVER IT. STOP THIS UNDERGROUND!!!!!!! Before i stop using this APP alltogeather 
I haven't had a problem, but I use the Android app, hope your problem gets solved. 
No clue what you're talking about and I'm on iPhone also.
Maybe turn off in app purchasing?? Just a random guess
