Today , I have tried again but still same issue remains. Yes ,I have checked my Email address it's correct and still didn't received any email in my Spam/Junk and inboxes .
Also, I didn't blocked any email address from sending me email.
Oh ! and one more thing I have changed my email thinking there might be some issue with the previous email and ironically I've received email change request on my previous email address. My friend is facing the same issue even though we have cross checked everything you mentioned.
