Keep getting pkg tickets – Go Mobile PGH Review

I have gotten several parking tickets EVEN THOUGH I pay through this app. Please figure out why the parking authority isn’t receiving info from you that I paid. Last week I was walking toward my car and a parking authority employee was taking a picture of my license plate. I asked him what was wrong and he said I had not paid for parking. I HAD PAID FOR PARKING. Not only did I pay for parking but I still HAD 37 MINUTES LEFT BEFORE MY PARKING EXPIRED. I showed the parking employee my app with 37 minutes left and he showed me on his machine that I had not paid. This is getting old. Please fix this. I’m going to have to delete the app if this cannot be remedied.
