Security tab

The security tab on the bottom row of my xFinity app on my iPhone has disappeared. This is the tab we used to view the security cameras. The only tabs that appear now are "Overview" "Services" "Wifi" and "Account". Previously, there was one that says "Security".

The cameras are still working, because we are getting notifications on our phone when there is motion. However, when we click on the notification, it just takes us to general page of the xFinity App (it should take us to a live view of that camera), and there is no way to see the actual camera. I'm not sure exactly when this happened, but it was definitely in the past few days. I have uninstalled and re-installed the app, and nothing has changed
