We just updated our mobile ads sdk to 18.104.22.168 on Android. Since then, we are having persistent freeze issues in all our games. While loading the amazon ad, the game just freezes. When we remove amazon ads, the game works fine. To see an example, just download https://play.google.com/store/apps/details?id=com.avishkarsoftware.battleinsky . Play it for a minute or so and you can see that the app starts freezing whenever an amazon ad is loaded. It gets progressively worse. Our users are complaining. Please help !
