Has iOS 15.2 solved the streaming problem with Xfinity on MacBooks with Big Sur

If you meant has Safari 15.2 solved the streaming problem with Xfinity, the answer was yes, but now no. I'm having trouble again logging in with Safari, but other browsers no problem.

I enter my login credentials, receive a message now connecting to your entertainment experience, then immediately brought back to the Sign In page. This happens over and over. The issue was fixed when Safari 15.2 was initially released. Not sure what is happening now. Are you able to login?

I'm able to login today to Xfinity Stream with Safari 15.2. Whatever the issue was for the last few days has been fixed.
