I've been using a modified version that I founder here a few months back and it was working great until recently. Wondering if there is a new version floating around or if anyone is still having success using an Xfinity app on either android tv or firetv?
Apk mirrio has new one but when you install it does not show up in app i think we need leanback version for Android TV
I had an old version and it worked alright, then about 2 months ago it stopped working. Would also be interested if you find a good one.
Try Fitzy TV. This is the best that I found for Xfinity users.
