It's been more than 2 years since people started to realize that this "feature" doesn't actually work:
https://www.reddit.com/r/applehelp/comments/qrr58d/hide_my_email_is_not_forwarding_any_emails/
It doesn't forward any emails to the email address you choose.
I have created Reddit and Tiktok accounts using Apple's Hide My Email and I can't remove them now because no verification email is forwarded to my actual email by Apple. Moreover, I can't setup 2FA on those accounts due to the same reason. Someone just tried to login to my Tiktok account and I guess I'm just supposed to sit here and see what they can do with my information because Apple won't deliver Tiktok's emails sent to my real email to setup 2FA.
How can't a +$2T company fix such a thing? It's embarrassing tbh.
I’ve used this feature many times and never had any problems.
