It is currently not possible/easy to refund a card-not-present credit card transaction that falls outside the scope of the transaction logs when the credit card is not present (eg: cancellled mailorder) and the two Clover minis are tethered without jumping through hoops.

Hoop #1: Unplug the USB tether cable, then initiate the refund on the merchant-facing terminal. A Manual Input button will appear after pressing Issue Refund. Plug the USB tether cable back in.

Hoop #2: Deactivate the tether app on the customer-facing terminal by pressing on the 4 corners of the screen. Unlock the customer-facing terminal. Initiate the refund on the customer-facing terminal. A Manual input button will appear after pressing Issue Refund. Run the USB tether app to return to normal.

Idea: When tethered, the merchant-facing terminal should show a Manual Input button in the screen where the refund amount is entered, below the Issue Refund button.
