Dear devs/studios,
Stop showing me ads while in the middle of a game or while I'm actively using the app. At least wait till the process is completed.

But that's a way of making money, while not asking directly for money, and people need to be fed sometimes
Usually if you buy something the ads go away since they already earned money from you.

It's one of the few profitable aspects of free to play games, especially if the game isn't big
