I had a third gen chromecast that was freezing up whenever my xfinity stream iphone app froze. Home wifi is fast. Bought the newest chromecast. Wondering if that and streaming from chrome on a macbook or pc would be a good workaround, knowing that the xfinity stream app has been problematic as of late.
Thanks for reaching out to the Chromecast Community forum!
