This is a common error that is seen when you quickly switch viewing devices. XFINITY On Campus only allows users to stream video to one device at a time. There can be up to a five to ten minute delay when switching between devices and you are able to have up to forty devices saved to your account.
If you see the error, please attempt our troubleshooting steps.
Clearing your browser cache from every device and browser that you've logged into is very important. Also resetting your browser to factory settings.
