BUG - Can't change Featured Listings. I change the queue with different products, Click SAVE, and it just reverts back to the previous items.
There have been a few posts about this recently. I think it is an Etsy glitch that has not yet been resolved.
I had no problem changing mine. You might try a different browser.
I've had this happen as well! It does eventually do what you want it to do, but you need to make sure that you've removed the older featured selections from your queue. Very frustrating indeed.
