usps 1st class won't show?

[gdtw]

I selected domestic first class letter, first class package retail, and priority mail, but only priority mail shows.
my product weight unit is oz. i tried 3oz, 9oz,.. etc but first class never show.

i registered and got use ID for the API, but i don't see anywhere to enter anything else. so the user ID (which looks something like 008XPRAV6385) is the only thing i've entered into the settings. i have entered my site URL for registration. I have not contacted USPS for permission like i've read somewhere. i just need to get the shipping cost. so i suppose i don't need to?

i've changed Tare from 0:3 to 10:0 and nothing changed.
i've changed Minimum Length to 0 from the default 8.625, and nothing changed.
i've changed 'Enable USPS First-Class filter' to false, and nothing changed.

i am using PHP version 7.4. and this is my site: https://xtrava.us

btw, also if i use flat rate shipping on 1 item, then order with multiple products will all have the same flat rate. how do i change that?

thanks

Please move your question to the USPS support thread, https://www.zen-cart.com/showthread....Support-Thread, including the version of USPS that you are using. I'll note that, as of this writing, the current version of the shipping module is 2022-08-07 K11e.

Also please ask your flat rate question in a new thread. Closing this thread.
