After finishing configuring my shop I proceeded to enter the VAT number.
I'm in Sweden, and VIES page confirms my VAT is valid, but shopify still says it's invalid.
I have tried both ways, only digits or with the SE (Sweden) in front, and it doesn't look to have any effect.
I have given it some time to see if it's refreshes or something, but after more than a week it still says is invalid.
What should I do?
I fixed it myself.
I did as follow:
I click on "I don't have a VAT number", I then input my number again, just the digits, no country letters, and then it took a while and it confirmed.
I guess I was too quick the first time I entered the number, and shopify´s system is not intelligent enough to recheck even if you click on change VAT number.
