unable to buy crypto with linked bank account

Description

I have recently added and linked a checking account and am unable to buy crypto with the account that I have linked unless it is below $1k. When it is over $1k it will not list my checking account in the drop down menu to purchase the crypto. My checking has more than enough funds to cover the amount I am trying to purchase (which is less than $20k). Does anyone know why? Paypal has TERRIBLE customer service, I have been unable to contact anyone on the phone as well as their message center. Please help!
