That depends on whether you are on the Handling Time option or the Door-to-Door option.
From 2019, sellers on the Handling Time option will only have to compensate buyers for late deliveries if they fail to meet their handling time. Otherwise, eBay will continue to compensate buyers.

Set listing handling times that you can definitely meet
Set your same-day handling working days and order cut-off times correctly
Use vacation settings or temporarily change handling times if you know you can’t ship on time for a while

With the Door-to-Door option for Guaranteed Delivery, sellers will be responsible for compensating buyers for late delivery from 2019.
For both options, eBay will continue to handle the customer service with the buyer.
