Oh by the way @CLOTHPADSHOP for the ones where vendors have confirmed they received the paypal payment, I have changed the status on the order in wp-admin from Cancelled to Processing. That then puts their order into their vendor dashboard. I check whether the item needs stock reduced too and update the product if so. I then manually adjust the Cancelled order email I received to say ‘thank you for your order’ and email to the customer and also the vendor. So much faff! Exhausted after today.
Let’s hope the techy fairies sort this overnight!
Might be worth you reporting this with Paypal via here:
