Etsy says if you get a payment processing notification to not ship the order until you receive an email stating that it is OK to ship. I have had several notifications this week some have been cancelled and some have gone thru but I have not received any email notification what so ever from Etsy notifying me one way or the other. Is there somewhere else I can look to find the info that it is OK to ship when it clears?
The order will show "Paid" when processing finishes and it's okay to send.
I don't know why you're not receiving the emails, but email can be glitchy.
It is best to check into your dashboard at least once a day to make sure. Once the payment has cleared the processing will disappear
