Buggy. Ads redirect to App Store every time I open app

This used to be a great app but now its too buggy to use and I end up just going over to my browser and searching the Internet. Every time I open this app now, I see the Mixology app for a split second and then I get automatically redirected to the App Store promoting a different app. I dont mind an ad here and there but this is ridiculous. Fix this bug and I may give the app another chance.
