I like this App but ???

What’s going on with this app ? I have an iMac.. I bought the 3.99 version to show me photo’s and info , you are suppose to click on points of interests and it’s suppose to give you photo’s and info, it doesn’t work . I have tried trouble shooting with there tech support by the way has been horrible. It doesn’t work and they can’t fix it.. Unless someone can give me a way to make it work on interactive mode or screensaver mode you are wasting you money cause it won’t work.. Please fix it or don’t offer the add on and charge people if it doesn’t work.. GET A FIX ..
