OK. Thank you - I didn't understand how the parcel mailboxes worked.

When you used the app to confirm the item had been sent, was your selling account updated - did Ebay know the item had been dispatched?

"There are two ways to be fooled. One is to believe what isn't true; the other is to refuse to believe what is true.”
Søren Kierkegaard, Danish philosopher (1813 - 1855)
