We too are receiving the above message indicating too many devices. We cannot access XFINITY Stream TV. The number of devices needs to be deprovisioned. Can someone please help? Also, please indicate how to prevent this in the future. Thanks,
My issue was resolved. Called 888-824-8988 and asked for level 3 support. The agent was able to clear the devices which resolved the issue. He also recommended remembering internet history and to not clear cookies or cache. Then, when logging in, you will not need to enter a device name every time. thanks.
