I created an issue on the active_shipping group but wanted to see if anybody here has run into this problem. I switched to ActiveShipping 1.4.1 to get the service code 2 working for Canada but now international rate requests are failing when asking for the commercial rates. If I don't set commercial_base: true they work just fine. Domestic requests for Commercial rates work fine.
Anybody else have this issue and come up with a workaround? It smells like a USPS api problem but curious if anybody else has run into this.
