Nomad Roasters review for Point of Sale

The card reader is always asleep. Trying to wake it up by pressing the power button once according to the onscreen message doesnt work. I have to go back or close the app, open it and login into the app again, or check the connection to wifi. Its just so inconsistent. Im thinking of just dropping this POS and move onto Square or Keeping it all on Venmo business and Zelle. You would think Shopify would have this fixed by now since this has been the biggest complaint from all POS users here.
