Everytime I try to log in from my new Samsung S4 from either Chrome or the Dolphin browser I get an error message. I've tried resetting the device, but it doesn't matter. This is not a problem on any other devices.
I have the same problem only when logged in to my wifi (comcast). If I switch to 4G, no issues. If I go to the full site, no issues. I am using the Comcast issued modem/router.
