Hey Alex! Glad to hear you're checking out the Visual Form Builder! You are correct, the Gift Aid add-on is currently not compatible with 3.0 forms, though this is top of mind for us and is planned to be introduced to 3.0 forms soon.

You can read more on our Add-on Compatibility Guide here: https://givewp.com/documentation/core/givewp-3-0-compatibility-guide/

I'd love to hear if any other feedback is coming up and your general experience with 3.0 forms! Feel free to share it with me at customers@givewp.com 😄
