I successfully signed up with EasyPost and created several Shipping Methods using UPS and USPS.  However, the only UPS service levels that work for my Odoo version 17 is:  NextDayAir, NextDayAirSaver, and Express.  I need to add:  Ground and 2ndDayAir.      

I had trouble with USPS Ground Advantage that is an option in Odoo.  That is the new service which replaces First Class for parcels.  When I deleted the "space" between the 2 words and clicked "create" I was suddenly successful with GroundAdvantage.

I don't think that I can spell "Ground" any differently.  ha ha

Thank you if you can help.  :)
