Difficult, tried to send my friend money, linked my debit card that had more than enough money and I kept being told I didn't have enough in my account, tried a lower amount, all the way down to$5 and they still said I didn't have enough money to cover it, the account I was trying to send from had $1200,and I was trying to send $400,I'm no Einstein, but I think it was enough to cover it and I'd still have money left, I just switched to PayPal and it went through right away, and Venmo is PayPal
