Hello I have the square where I can print receipts terminal and now that I have had it for over a year. A random point in the day my machine will not process payments. It random there is nothing wrong with my wifi or the clients card. Why is this happening. The machine will look like it’s processing but it will just think and then fail. Why is this happening how do I prevent it. Why is it only doing this in the last month? It’s really annoying for me and the customer when I have to restart the machine to take the payment. Please help
