Never works

I been using this app ever since I found out a out it and it never works 95% of the time. I Bought like 5 McCafes and it barely wants to scan and give me credit for my purchase so I will never get to 5 punches because it never works... When I pull up to McDonalds to purchase my kids some food the app magically stops working and I dont get to use it.
