I had an item set to "Manual" Renewal option get Auto-renew sold listing fee Feb 7, 2023 around 4am EST - Is there are bug?
Auto/manual renew and renew sold are two different things.
If you have a quantity of more than one on a listing, each time one sells you are charged 20 cents to relist the remainder until there are 0 left.
The listing is good for 4 months or until it sells. You sold one so it automatically renews so you can sell more. You can change it to only 1 available but then it won’t show until you relist it.
