Venmo payment is working intermittently on skyapi

We are using Skyapi BBMS checkout payment. Venmo payment is going through intermittently. Went not going through the QR code screen for venmo does not go away to do the payment.

Also there is an error in the browser console "[Violation] Permissions policy violation: upload is not allowed in this document". Attached is the screenshot. Please let me know what is the issue.
