My Mpop cash printed a shopify $100 when upgrading the POS

[CDesla]

Yesterday I set up the new tap card reader on my mpop cash register, and found out that I had to upgrade my shopify POS to the new shopify POS app, and when the upgrade was done, my mpop cash register printed a $100.00 Shopify bill. It as a number on it, can this be redeemed on anything shopify? Anyone else  had that happen?

I don't even think I upgraded the app but I had the same thing happen. I have no idea why!? Anyone know what this means?

Mine did it too?

Seriously, You think Shopify is going to give money away. They can't even get there POS to work properly.

Just wait until you have to do a return on a cash sale with no receipt.

Or a second return or exchange on the same order. NOT

Maybe it's for a second swipe reader as a back up because your first one will die at the worst moment.
