This is purely related to Kagifeedback.org website.
When signing in with Apple as a SSO provider, Apple creates a unique (privaterelay) email address that allows only kagifeedback to email that address. I understand from Apple that up to 5 different pre-approved email addresses of the vendor are allowed to email the privaterelay address.
However, my email zwtz8gbqhf@privaterelay.appleid.com is not receiving any emails from kagifeedback.org. This also means I can't change my email address (to change email address, I need to set a password, for which I need to be able to receive email).
I escalated this to Apple, but they are placing the issue with Kagifeedback and not with their privaterelay. I'm not facing this problem with any other websites where I sign in with Apple, and I tried the same thing with my wife's apple ID and kagifeedback, and she is also not receiving any emails sent by the website.
Any clue?
Thanks
