Hello, recently upgraded to the XE75 and it's been excellent so far.  A massive upgrade from my 10 year old router.  I'm having a minor issue with the app not showing accurate traffic download/upload speeds.  In most cases traffic be idle when I know there is network activity. For example my son is steaming a show and the download/upload speed is zero.  I restarted the system, redownloaded the app and even downloaded the app to a new device, same thing. Both firmware and app are the latest release and the traffic meter worked perfectly until yesterday.  Any ideas?
