Issue I noticed. On the old version when something was sold out, there was a banner that said "renew sold" above the item. After you renewed the item this banner went away, and you had the option to "renew" or "edit".
After I had a sale, I used my phone and hit "renew sold". It renewed, but gave me no indication that it did successfully. The "renew sold" bar is still above the listing, even after pulling down to refresh.
I hope this is a bug! I'm on the go a bit, and this makes it harder to see what is actually sold out, and in need of being renewed.
