Hello there, sorry for a silly question but I just wonder how to add Admob ad. I follow the video and they said on the UI phe you caan checked to add Admob option. But which ui should I add them on. Sofar I have UI for title and UI for in game and UI for gameover menu. ATM I check the Admob option on the gameover UI only. Is this the right way to do? or should I check them all on every UI page? Thanks!
