Despite having all the proper settings applied under our Shipping options - USPS calculated, retail rates, express and priority mail, handling charge, and the same USPS username we've been using for 2 years now - suddenly the only shipping option that's available during checkout is free shipping. See attached screenshots. We really need the USPS calculated shipping options to be applied but they're not even available to customers to select and I have no idea why.
I'm on hold with USPS now to see why our API is suddenly disconnected but in the meantime, I'm wondering if you have any insight as to why this keeps happening; Last month, we kept getting the "no valid shipping options" error. Had to call USPS to reconnect our API. This time, without even changing our settings since what happened last month, we're giving away our shipping costs all together. Since this started happening the other day, I have tried checking different boxes within the USPS settings like flat rate box options. But I don't know what else to try. It still just says free shipping every time during checkout.
Please advise: How do we get our USPS calculated rates applied to checkout? And how do we keep these errors from happening a third time?
