Solved for me. I fixed my Chrome. Here is what I did. I wanted to cast from Chrome and nothing was working. I did all the cleaning history and cache. I updated Flash. I even did a system restore to a date I know everything worked. Nothing helped. Here is what finally did:
I went to Settings // Advanced // Privacy and security
Use a web service to help resolve navigation errors
Use a prediction service to help complete searches and URLs typed in the address bar
Use a prediction service to load pages more quickly
Protect you and your device from dangerous sites
I left everything else off
But here is what I think did it for me:
On the same page two categories down is "Content settings" I opened Content settings // Cookies
I selected "Allow sites to save and read cookie data (recommended)" leaving "Keep local data only until you quit your browser" and "Block third party cookies" off.
I noticed "Search cookies" 4 lines down. I typed in "xfinity"
Several cookies were found and listed. I deleted (trash) them all. I then closed Chrome and reopened it. I went to MyXfinity, signed in, found I want to watch TV Online, went through the streaming sign in, named my device, and went right through the dreaded "now connecting to your entertainment experience" page into Xfinitystream. I about shouted. My arms did go up as if I'd done something great.
Hope this helps you
