Hi there I've added support now for VENMO for PayPal Checkout users but this is only available in the v7.4 "Advanced" updater for now. I could add that to the v7.3 if you wanted to use PayPal Checkout as it's only a configuration setting. But you are using PayPal Standard and Express and with both of these the payment takes place entirely on the PayPal website and you get the options that they present. What I understand is that VENMO is supported by these payment options where applicable. But it would need to be a mobile browser with VENMO installed on the mobile.
