Etsy is telling me I have 7 listings due to expire. I stopped using the manual renewal option YEARS ago. Bizarre!
Another recent glitch. I found 3 listings with incorrect quantities, less than what is in my inventory.
I frequently audit my inventory and check remaining inventory counts when an item sells, otherwise I would have not noticed the incorrect counts.
None of those 3 listings with the lesser quantities were refunds or cancellations where the quantity in the listing would have to be adjusted.
I wonder what other bizarreness will happen.
Regarding the listings that are due to expire - There's been a bug in the system for a long time where listings that were supposed to expire on a certain date didn't expire and stayed active for 3-4 years. Many sellers, including myself, have listings that never expired. That bug has been finally fixed, so those listings will now expire and you can renew them if you want.
You mention that you haven't used manual renewal for years, but maybe those listings set to expire were on manual back then and overlooked. We are not going to be charged the 4-month 20c fees for the time our listings remained active.
