I'm building a game in Unity that uses AdMob ads. In the app I only have one screen (a map with objects). I want to add a rewarded ad to 1) speed up an upgrade 2) unlock boosters. They all are on one map (one activity). In this case should I use 2 ad units or only a single is ok? I am aware that I should use one ad unit per activity but how does it apply to my case?
** can google punish me (make some limits) for too many requests if I use more (10+) ad units in one screen?
