Thank you for your reply although this is not a good outcome for sellers as we will all have to relist the items again once they have been returned and hope that they will sell again.

Coincidently or not, I have just had a tracking update on my business account which was a C&C to say that Evri have attempted a delivery and there was no safe place to leave the parcel ( a shop!).

I think the issue may not just be affecting parcels sent by Simple Delivery.
