I'm actually having loading issues as well. Screenshot attached. I think something is going on with Duma.
I am getting the same message after
1: clearing the browser cache/cookies from Chrome, Microsoft Edge and the Opera browser.
2: having the same issue on two machines (one machine is a brand new Laptop fresh out of the box)
3: I've also rebooted the cable modem and XR700 twice.
Please advise
