Is there an issue accessing the Data Usage page?

Good Day! When I go to https://customer.xfinity.com/#/devices#usage  and login, it hangs and eventually logs me off.  There are no ad blockers or such in place.  I was happily using the Xfinity app until now, but you pulled it from my phone saying the phone was too old (2021, Android 11).  Can you lend me a hand and, no, I don't need a new phone.  Thank you.
