hi,
There could be many reasons why the rates don’t show up in the cart page, here’s few things you need to check,
1. make sure your products have weight and dimensions, both simple and variations.
2. Make sure the real time rates are enabled in the plugin settings.
3. Make sure you have entered the valid UPS API Credentials.
4. Make sure the required services are enabled. Ex. UPS Standard, Worldwide Express, Ground etc.
5. Make sure you have updated the ship from address correctly and the address match the country your account belong to and even in the woocommerce General setting it should be the same country.
If you still face issue please turn on the debug mode in the plugin settings, and while calculating the shipping cost in cart page copy the debug data and update it here, please make sure you remove the UPS Credentials field.
