Not receiving password reset emails from any external accounts

Hello, I have recently stopped receiving any password reset emails from external accounts such as Hulu, Skillshare and others. I have not changed any settings and have even added email addresses to my contacts to see if that would resolve the issue. I have also logged in directly to Xfinity through a web browser to see if it was an issue with my 3rd party app and still nothing. I’ve seen other people are having the same issue. Please help resolve this as it makes it impossible to gain access to my accounts with other apps/companies.
