You should read all of the email.
Feedback (as always) will be irrelevant as it is voluntary and there is no mechanism for buyers to mark items as received.
I don't know why so many posts mention feedback; it is not mentioned at all in the email received today.
If tracking shows delivery, you will be paid 2 days later.
No tracking, you will be paid 14 days after posting.
"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)
