Can't access Comcast email since password change

I was prompted to change my Xfinity password. I did so and have no problem getting my email on my MacBook after changing the password in mail app. I attempted to stage the password on my iPad (new iPad pro0 and my iPhone 14. I am unable to access my email on either. I deleted the account, restarted the devices and attempted to read the Comcast account, entering the new password. I get an error message stating that there is no password entered and I need to go to the mail app and enter the password. Of course the account isn't added so that is a non starter. I spent over an hour with apple insisting it is an Xfinity(Comcast) problem. That seems curious given that I have no problem accessing my email on the web. The email security setting on Xfinity is set to allow third party apps like apple mail access. Comcast has been my main email address for 25 years, so changing is a hassle I'd like to avoid. After over an hour with an Xfinity rep all I was able to do was answer him multiple times that I could access my email on the web. I'd appreciate help with this
