I had a card transaction and after removing the card, the pos system still said to remove the card. The card had already been removed and I could not get out of the screen. After trying everything I could think of I powered down. Now I can’t log back in (Error 0) message.
Hey @Kalicea ,
Welcome to the Shopify Community!
Are you still having trouble logging into your POS? If so, I suggest manually changing the PIN via your Shopify Admin. Follow the steps below to create a new PIN for your POS app:
-
From your Shopify admin head to Settings > Users and Permission
-
Then click your name under Store Owner
-
Scroll down to Point of Sale access
-
Here you can generate your PIN that will be used to log into your POS app on your mobile device
Moving forward, if you experience performance issues with the Shopify POS app, then there are some common steps that you can take to troubleshoot them below:
