Hello,
No, what I'm saying is that :
The orders information seem to be correctly sent to the USPS platform, but note that setting the "Use product dimension" to no will result in packages dimensions not sent to the USPS platform, so they'll only be able to apply weight restrictions.
So if you want USPS restrictions to be properly applied, you should set that option to YES.
If i set it to yet...I seem to get the same results, so nothing is changing.
If even clearing your cache and changing that option value doesn't change the final result, then that mean the USPS platform isn't properly applying their restrictions and returning rates. We actually don't have any control of values returned from the USPS platform as we can only send them as much information as we can about your customers orders.
So contacting USPS about your issue can be a good solution, we can eventually help you check the code sent to the USPS platform if needed.
Kind regards,
Mohamed Thelji
