iPhone Compatibility issues – Etsy: Shop & Gift with Style Review

Hi, I've been having issues since the new iPhone update. I actually didn't update my phone yet but the app keeps saying "uh oh there was a problem. Try again" however when I click try again it still doesn't work. I've noticed it's only when I'm not connected to wifi that I've had this issue. Or when I go from wifi to no wifi. Thanks!
