Dipping a card in Offline Mode freezes the Terminal App

Can someone try to duplicate this bug, please?

Disable automatic offline mode: More | Settings | Offline = Off
Load shopping cart with an item
Simulate network suddenly failing by turning off Wi-Fi: More | Settings | Hardware | Network | Wi-Fi = Off (red stripe appears across top)
Attempt to process payment: Checkout | View cart | Charge
(Notice that you can return to the cart with "X" in the upper left corner - and then return to the charge screen - as many times as you'd like.)
From the charge screen, attempt a dip; get shown “Unable to process chip cards” error.
Terminal is now unusable: “X” in upper left corner does not return to cart as it did before the dip; “Split Amount” & “More” do nothing . Terminal must be rebooted using side power button.

I can reliably duplicate this on our terminal running 5.51.0076 / 6.54 . The bug does not appear for a tap: the terminal seems to ignore the card.

I have reached out to our engineers and asked them to investigate this. Sorry for the delayed response.

Are you still seeing this happen?

@Lynn_TRU Is this happening with all cards or certain brands of cards?

@Lynn_TRU if you could get a video recording of this happening, that would be helpful as well.
