Xfinity Account Access through iOS App using VPN

I’m trying to access my Xfinity account through the Xfinity My Account iOS app version 1.58.11.20220804222542. I’m doing this on a 512 GB iPhone 14 Pro Max running iOS 16.1. And I’m also running NordVPN iOS app version 7.21.1 (313)  with the VPN enabled using their Nordlynx protocol. After I login to the Xfinity app using my user I’d, password, and 2FA text msg code, I get an error message saying “You are logged in but we are unable to access your account details. Would you like to try again?” I’m also given to buttons - Try Again and Sign Out. Hitting Try Again gives the same error message. Sign Out results in me being logged out. If I disable the VPN, I can access my account through the iOS app just fine. If I have the VPN enabled and access the Xfinity web site through the Safari browser, I can also access my account just fine. So, this seems to be a problem in the Xfinity iOS mobile app. Can you help or give me some ideas on what to do? Thanks in advance for any help you can give.
