Bubble's Email Validator Plugin is Not Letting Users Sign Up

I am using Bubble’s Email Validator Tool in my Sign Up workflow and I just discovered that it is preventing some people (with perfectly valid emails) from creating accounts.

I just testing it out with my father, who has an email with his business domain, and it is telling him his email is not valid. So, it’s not a basic gmail or yahoo email, but it’s a real working email.

Has anyone else run into this? Anything I can do to fix it with the Email Validator Plugin or another way to validate that emails are real?

It is buggy.
What helped me was using a yes/no state and two “When” workflows on email input that change this state - when email is valid and when it isn’t valid.
