Paypal Reversed Payment

Buyer purchased on Thursday.  Paid with Paypal Friday.  My Sold Summary shows a reverse arrow under the Payment column. The View Paypal Transaction link shows payment has been reversed.


I checked my Paypal account and the payment has been refunded to buyer with a note stating  "Paypal reversed this payment due to a dispute or after review of the payment was complete.  The money has been returned to the seller's Paypal account."


I sent a message to my buyer asking if they were aware of this reversal but haven't heard back yet.


Has anyone else had this happen?
