Xfinity connects to chromecast. Says ready to cast but does not show program

@XfinityTravis​ Don't you think I have been through every help page Xfinity has to offer???? Do you think your consumers are unintelligent and don't know how to troubleshoot? Don't you get that the people posting here know how to cast and giving the instructions as an answer to a software issue...is treating us like we are imbeciles? Most of the people having this problem is that it had been working and suddenly stopped or it works with all other apps yet not Xfinity. Doesn't that already tell you that we and I already know how to cast. So why send instructions on how to cast as the solution?

I have also scoured the internet for solutions, which led me to this forum. On it I have found SOOOOOOOOOOOOOOOOO MANY people with the exact same issue and not in a single post including this has Xfinity offered any viable solutions other than pat and generic answers such as the one given above...attempting to give the appearance of caring and helpfulness but in the end not providing anything that is actually useful, even remotely helpful and not even close to a solution. So let me lay it out for you. I have TOP OF LINE equipment, ALL minimum requirements are exceeded, and eligibility met. All apps are up to date. Yet your service is not working. 

Additionally, there was ONE DAY I was able to stream several shows from Xfinity on my macbook pro to the TV. It worked well...then suddenly never again...same TV, same Chromecast, same computer, same Xfinity website. And it has NEVER Worked on my iPad Pro 

Another thought to share with you...regarding how ridiculous it is sharing a link on how to cast was even an option your thought to share...is that if you read the post clearly. It explains how the app and website say they are connected and casting...yet the 3 dots showing is connected never stop displaying...so obviously how to cast is not an issue. Please if you want to provide customer support post info that actually supportive and addresses the issue posted. Not just the basic generic answer Xfinity has been posting over and over that hasn't solved this ongoing issue

Please also keep in mind that the ability to cast from either the Xfinity Stream App or the Xfinity Stream portal is provided as a courtesy in addition to your subscription services.
