Hey there @maddhattercaps,
Thanks for posting here in the community!
If no rates are appearing, it could be because there is not enough information provided yet to populate in that rate browser. This may not be the case, but i've seen it myself a handful of times so always good to double check! If there are other instances that our community members have seen that produced this behavior, we would love to hear about them to help out!
Once you have double checked and confirmed that all information has been submitted, and no rates are pulling in, my recommendation would be to reach out to our support team. They will be able to check into the backend of the carrier integrations to see why those rates are not populating as intended. You can reach them to start that investigation at Support@shipstation.com or via the chat widget.
I hope this helps!
We are having this same problem. The spinney thing just spinnnies and no rates appear. This has been happening for us for a week now. We are also having the problem of not being able to generate any packing slips or labels for shipments. This is quite appalling atm.
