Solidus 2.11.17 does not support GBP currency

[keferboeck]

Solidus Version:
2.11.17

To Reproduce

/initializers/spree.rb
config.currency = "GBP"
(instead of USD)

In the Database, run the following queries to (against the sample store) to switch from USD to GBP

update spree_orders
set currency = "GBP"
where currency = "USD";


update spree_prices
set currency = "GBP" 
where currency = "USD";


update spree_variants
set cost_currency = "GBP" 
where cost_currency = "USD";

Current behavior

When currency is set to GBP, the checkout process does throw an error past the "address" step. The error message is:
"We are unable to calculate shipping rates for the selected items."

Expected behavior

Once the address fields are correctly field in, clicking "save & continue" should take you to the next step "Delivery".

Screenshots

Desktop (please complete the following information):

• MacOS Big Sur (Version: 11.2.2)
• Browser: Chrome Version 104.0.5112.101 (Official Build) (arm64)

Additional context

I tested the behaviour against the sample store, as well as products we added. That shop was build from scratch without any sample data. The error appears on both setups. I backed up the databases if that is of any help, but I am sure you can easily reproduce it yourself.

You need to update the shipping methods as well, as they are all likely configured for USD.
