Hi, We have just connected Paypal sandbox to Braintree sandbox account. When we test to make a purchase in frontend with Paypal via Braintree, we get "Sorry we cannot connect to PayPal. Please try again in a few minutes." in Paypal's popup window. We are using Magento 2.1.8 as platform with its default integration to Braintree. App has been created in paypal sandbox account, and credentials have been added to braintree sandbox account and braintree sandbox credentials have been added to payment methods in magento admin area. We use onestepcheckout. Does anyone have any idea on what needs to be done to make this work? /Sabina
