invalid shipping error

[Mark Hood]

After playing around with getting shipstation connected to my store via the api miva connect my shipping methods are no longer working during checkout.

They all still work if you use either paypal or apple pay.

Support has not been able to fix this so I'm hoping someone else has run into this...

Adding onto this the shipping estimator does work correctly on our basket page.

This sped things up. Miva support resolved this. Apparently I managed to deactivate the wrong module... whoops
