Are we supposed to actually be able to test the installation and API requests? The USPS installation went fine, got the USER ID and everything. In Zen Cart, red bar at top says USPS is in testing mode. But when I try to test the Shipping Esimator, the USPS is not a choice of shipping methods, and no testing occurs.
I'm wondering if this is because we are not actually supposed to be sending the test API requests to the USPS server (supposed to only wait for USPS switch to production), OR if I am doing something wrong while trying to test. Thank you.
