ABSOLUTELY UNACCEPTABLE 😉 I just bought ONE YEAR SUBSCRIPTION. How can you be showing ads with a PREMIUM SUBSCRIPTION? It is totally UNACCEPTABLE and Google Play has the LEGAL DUTY to stop you from exploiting subscribers. You owe your PREMIUM customers the LEGAL DUTY to allow them unencumbered use and enjoyment of the product they paid for.
