Status 400 Cash App Payments not working

1 - the CashApp account I thought it could be the card. However I added money to the CashApp account from the card and that went through fine. Once the money was added I tried again but still getting the same error.

I verified my account is activated.

2 - I tried different cards and like I said I even tried adding $ to the cashapp so it has money and then use that balance to pay but declined.

3 - This is very interesting. I am in testing mode and I set the price at $1. I was unaware that Square Up has a limits. What are the limits for it being too low?

4 - Yes your right about some cards having restrictions. This is why I added the funds to the cash app account so I can use that balance.

How can I reach out to Square’s support team?
