OK, so a few days ago, a Navigation app (Im assuming it's google navigation started popping up randomly and telling me that "you need the following license to accomplish this trip" then gives me the options to choose BUY, VOUCHER, SYNC LICENSE or CANCEL... cancel takes me back to the app only to have this pop up again. SYNC, BUY and VOUCHER all take to an in app purchase system. Question is.. how do I get this app to stop popping up, and why is it all of a sudden trying to get me to buy it? (ive used google navigation before and it worked fine, never asked me to buy anything.).. Any help?
