Comcast email using Apple Mail not accessible after Sunday November 1, 2025

As of  Nov 1, 2025, I am no longer able to access my comcast email on my iPhone, iPad or Macintosh.  There was no notification from Xfinity, it just ceased to work.  I can still access my email via the Xfinity web site but not on my devices.  I was using a Pop account.  I had been a Comcast customer for many years in New England and retired to Green Valley, AZ and do not have Comcast service here.  I was thankful to be able to still keep my Comcast account because of the many applications linked to this account.  Any help would be appreciated.
