I am not receiving certain emails on my msn.com email account

In the last few days, I noticed some mails are not getting to my mail box and I have not changed any rules.

I sign up for a Nike.com account and failed to receive the OTP. I tested with my wife's msn.com but she received. I tested with a Gmail account and received too.

I have manually added Nike.com notification accounts to safe sender list but still received nothing.

This is only 1 example, emails I used to get for the previous week now do not come to my mail box.

I have checked all my rules, security and do not find anything wrong. My storage is not full as well.
