Venmo Payment Error

We are using 5.5.2 Stylist.  I have a customer who paid by Venmo and I received their payment in my PayPal account, but their order only shows up in the shopping cart, not as a completed order.  They did not receive an email that the order was placed.  Any ideas how to resolve this issue?  Thank you!  Melissa

I am also getting an error on Venmo payments.  Error message is:

"Sorry, but your transaction was not successful. Try again if you believe this was in error.  If you continue to have problems, please contact us. "

I am never taken to the Venmo website.  

Other Payment options such as Apple Pay , G Pay and PayPal work.  

Many people using Venmo without issue with the PayPal Complete Payments.

You will need to check PayPal logs to see if there is an error. Click here on how to do that.
