Previously on the Station 2018 model the customer would be prompted to select a tip amount after the sale had processed. On the Station DUO the tip prompt screen pops up on the customer facing device after the Merchant clicks "charge on connected device" before the transaction has actually processed. I have had multiple of my merchants complain about this workflow because customers selecting the tip amount and leave because they think they have paid. My merchants have unfortunately lost a couple of sales because of this. They are high volume Coffee shops so they are unable to monitor whether or not the sale goes through because they immediately make drinks after they click "charge on connected device" in the register app.

The simple fix to this would be change the tip feature to prompt on the screen after the transaction has processed just like it was before on the 2018 model. Or even making this feature editable to appear before or after the transaction.
