Hi we have just download a trial version of you braintree payment plugin for nopcommerce 4.10 for testing it before proceed to purchase it. We already set up a sandbox in braintree and make the setup . So when using a recurring product (we followed very carefully you instructions) when we submit the payment with demo (but right) credit card detail in the order process , we take the above message
"DropinError: No payment method is available."
We have also enable vault and Vault manager because they are appropriate for braintree for reccuring payments.
