Love App. Hate constant upgrade notice

Just bout the Worktime App. As soon as I paid to upgrade from the free app I instantly started getting upgrade to the new App as soon as I bought the one I did. Seriously, delete the old one if its irrelevant now. Im not paying twice for the app I just got so please remove the notice required to X out of every time I open the app. Frustrated. On the positive side I really do love the App I have. Its almost exactly what I was searching for so thank you. :-). (Not meant to be negative. Just need to let you know what needs to be addressed).
