Why would you take my money!?

I had this app for a really long time and it was great until about a week or two ago. In this app there is this thing called skin studio where you can make or change a skin and upload it to minecraft.net. Well the skin studio app came out and I didnt have to buy it because I had already but the in app skin studio in this app. Well a week ago in had an update and now in this app it wont let me use the skin studio. It says I have to go buy the other app!! When I already paid for the in app skin studio for this one! I really dont want to pay another $3.00. I know its not much but I dont want to pay for something I already have!!! This is dumb and I want my money back!!!!
