I have an issue with Clover duo 2nd when taking a payment from customer. Payment terminal keeps going back to tip select screen even though the customer already selects tip amount and pay with credit card. So, it makes double charge for same order most of time. This duo 2nd device is brand new, and network is super strong. How to resolve this problem? I was contacted to clover tech team, and they didn't give me the proper solution for this issue.
