Fix in-app purchase for existing Android app

Job ID: 35786566

Budget: €8 – €30 EUR

My developer for this photo editing app released a completely new version with multiple in-app purchase options (1 month, 3 months, 6 months, 12 months) and also lifetime purchase to remove all the ads in the app.
After I published this new version on Google Play, people started to buy the lifetime option and complained that they still see the ads after buying the lifetime package.
I need a skilled developer to help me fix this problem. I can't get in touch with the original developer to fix this app, he doesn't respond to my messages for several months now.
