Yes I still need help on this.
A buyer can click the “cancel order” button indefinitely on appointments and events and digital downloads.
This means they can get a payment reversal even if they go to the appointment or get the download.
There is no ability for a seller to stop this as the changing order status functionality is disabled for these listing types.
I believe the solution is to remove the cancel order button, or enable order status changes. The latter being the preferred as it allows sellers more flexibility and
options.
This issue is linked to my post on digital downloads as essentially its the same issue: Digital Download & Bank Transfers? - #3 by franos
