We've been having fun with the new USPS changes effective July 28; when they first made the change we were still seeing Flat Rate Boxes as an option, with the new 1 day, 2 day, 3 day tags. Sometime in the last day or so they stopped appearing as an option all together. Priority mail and others are still showing.

We don't have the flat rate boxes named in the RTShipping.ShippingMethodsToPrevent appconfig.

Is anyone else experiencing this issue?
