It sounds like you just want to continue complaining. If you're waiting for Xfinity and Roku to fix these problems, then that's never going to happen. Both companies have already stated that it's not their problem and they have no interest in looking into it any further. I offered a few workarounds. If you don't like them, don't use them. You're obviously way smarter than I am. But I'm enjoying nice clear non-interrupted TV using what you claim is subpar cellular Wi-Fi. My upload and download speeds are almost twice what Xfinity was. I haven't purchased any fire sticks. I was relating someone else's information that they worked better than the Roku box when it came to the Xfinity app. Again, if you don't like my suggestions, you don't have to take them. It sounds like you just like to complain. Good luck with that. And as far as cost goes, I'm spending the same amount of money using T-Mobile home Wi-Fi and the Hulu live TV package, as I was with the ever-increasing Xfinity bill. So for the same money I get far better quality internet and TV then I did with the 1970s VHS quality Xfinity TV picture. I have no interest in paying Xfinity extra for HD or 4K. Have a great weekend. Go 49ers !!
