Hi @anpeter,
Good morning, and thank you for your feedback. We are happy to help😊.
The plugin basically supports the block-based checkout, but it’s not fully compatible yet. We are still bringing all the features there. For now, the field is showing, and the VAT exemption, along with some other features, is working. Full compatibility will come in upcoming updates.
Please make sure you have enabled the Checkout Block Field option in the Admin & Advanced tab to have the field appear for block-based checkout.
Best regards,
