No emails are displayed when I use the Xfinity app on my Android phone

When I sign in to the Xfinity app on my phone, I don't see any of my emails. I sign in to the app and tap "Check email", then I am asked to sign in to my account again. I then get the message "We are now loading your email." It looks like my inbox is being displayed, but there are no emails. I've cleared the Xfinity app cache, uninstalled the app, re-installed the app from Google Play, and restarted my phone. The same thing happens. Everything was working fine until yesterday (6/27/2026).

I can view all my emails when I use Firefox on my phone.
