A good app made awful by invasive ads

It was a very good app till they installed the invasive and insistent ads that pop up for a fixed amount of time, you cannot get rid of them till the timer goes, and then, on my ancient iPad 2, the whole app locks up in ghostly white. I understand the need to make money, but dont you need a functioning app first? I dont see this in ANY of the big American and British newspaper apps. Dreadful. I wont be a customer much longer, then how much revenue have the ads brought you? Ads only work if you have CUSTOMERS. Put it back like it was.
