ShipStation is great when it works, but when it doesn't, it's a business critical tool our of action.Support are useless, giving generic responses constantly and not reading the body of the message. When you can eventually get through to 2nd line support, they ignore you.Business critical tool out of action for a month now, with no fix in sight and ignored emails.It's a great tool, but they really need to overhaul it top to bottom. Constant issues. Currently cannot create manifests or edit addresses. Last month, couldn't change the postage service unless I set the address to a different country, and then changed it back again.
