Thought it would be valuable to mention but I was selling on Vertex and the buyer reversed the PayPal transaction, Vertex refunded me 80% of the transaction. The support is really good, they helped me as soon as I opened the support ticket.
I don't think using Paypal in exchange is a good idea, scammers are everywhere. They often open dispute to be refunded and make my paypal account frozen/ limited.
You still lost 20% and it is a large amount in a big transaction.
