Why is there no shipping speed showing up?
It seems that you need to review / configure Shipping speeds for your orders.
So, there are two ways.
1. Amazon real time Shipping speeds: This depends on if your current Shopify plan supports the feature -
carrier calculated services. Kindly reach out to Shopify support team on this. Once activated or this is part of your current Shopify plan, kindly follow t
he steps below: Open our app>>Configuration>App settings>>Show All Amazon shipping speeds to Customer>>Select "Yes" and save.
2. Shopify's default Shipping speeds: You can enable these shipping speeds from Shopify.
The steps are:
Shopify admin store settings>>Shipping and delivery>>Manage>>add rate to an existing Shipping profile/ Zone
There you can add Shipping speeds and its rate based on weight or total order value.
