Xfinity Apps and Mobile Do not work with iPhone or iPad

None of the Xfinity apps (MyAccount, TV Remote, Stream) or the website chat function will work on either my iPhone or iPad. My apple products are on version 15.6. The apps just have a spinning load icon that never finishes. If I turn wifi off I can get the apps to load but they won’t do anything since I have the wifi off. I’ve restarted my phone and apps to no avail. I even had to shut off the wifi to be able to sign into this forum. Please help!!!
