iOS 15 Beta: Hide My Email. Users can't receive emails

We've been testing the beta version of iOS 15, in particular, the Hide My Email feature. We registered on our company's website using the feature and we haven't received any of the automated emails (Confirmation, Welcome emails, etc). We also tried sending non-automated emails from our company email addresses and third-party email addresses, and none of those emails showed up in the mailbox.

Has anyone experienced similar issues? Is there a way to make this work?
