I am experiencing a problem with Magento 2.4.4:
I have created two customer groups: Bronze and Bronze_Vies (for European customers with valid VAT number). The Bronze_Vies group should be tax-free, but:
New users: They are not always correctly assigned to the Bronze_Vies group, even with a valid VAT number.
Tax calculation: Even if assigned to the correct group, some customers still see taxes in the checkout. This happens inconsistently and sometimes the taxes only appear after choosing a payment method.
I need to understand if this is a known bug in Magento 2 and how I can fix it.
