Since last week my stats for the prior day are showing the current day plus the day before. And on multiple devices
Mine haven’t done anything like that, however they have been messed up with one thing or another for quite some time.
I find stats are rarely correct. For example, how can an item say no views when it's been favorited? I've even had items in carts or sold that show no views. There's always some glitch and Etsy doesn't care.
