I like PayPal, it has a high security standard. Except when I am the one suffering a chargeback for some flimsy reasons.
Polymail might be a bit more popular than PayPal. We know about 1 link to it since March 2021 and only 1 link to PayPal. We are tracking product recommendations and mentions on various public social media platforms and blogs. They can help you identify which product is more popular and what people think of it.
(I live in USA) When I go to payments under my shopify account to add paypal as a payment method I am having trouble doing so. I first click activate paypal > activate paypal express checkout which directs me to a "security challenge" (confirm I am not a robot). Then it just brings me to paypals website (paypal.com/us/home). When I sign in nothing happens, I am just on my paypal homescreen. Source: over 1 year ago
