Hi Edith,
Would you be able to clarify if this issue is with the ad player, or with the game itself? If its with the ad player then I am afraid there is nothing we can do. We use a service to display ads in game and as a result we have no control over how it works. If this is however an issue with the app then we can look into it, would you be able to provide more details on which back button you are referring to? If you have steps we can follow then that will help us find the issue. Any screenshots you may be able to provide us would be really helpful too!

Hi Conix, I'm afraid I can't identify this myself, but regarding the back button, I am referring to my handset's back button. So once the ad's timer ends, I could earlier use my phone's back button to exit the ads. Now I need to press the cross symbol that appears in the corner. Not a big deal per se, but just a bit inconvenient with folks who have giant fingers
How does everyone exit the ads? (And come to think of it, I never figured out how to exit the app itself either. Lol)
