If an existing client changes his VAT region, for example first his address was in France and he changed it for another order to Poland, then our initial VAT posting group that we linked to that client doesn’t change with the second order.

The region/country on the second order is correct but the VAT posting group that is coming from the client card does not change with it.

Is there any option to counter this problem that is now standard in the Shopify connector? Or are there any updates coming that could counter this?

Because our client has to check those manually and change them manually if the order could change the client card and with it the VAT posting group that would solve our problem.
