Yes they were working fine until recently. We got a new ipad and suddenly they no longer worked. 

Hello @Commissary!

Gift Cards are tied to the account that ordered them. This error message would only show if you tried to load another businesses gift card. I'm taking a stab in the dark here, but it sounds like you might have created a new Square Account when you got your new iPad. Do you have multiple email addresses that you use? 

I'm having the same issue. We just changed ownership and a new account was created. How do I get these cards to work with the new account information?

Hello @Essencha! 

In this scenario our Customer Success Team can migrate the gift cards to your new Square Account! Reach out to them via email to get a case started. 🙂

Wonderful! Thanks Chad.
