I am using the latest version of this app on my AFTV. Seems to be working okay, as for streaming issues, well, this is comcast we are talking about. When I had HD TV from them, it looked like I was watching a blocky SD TV whenever people moved around on the HD channels. So I am not surprised when at 6pm my time I can not watch WWE Raw live on the USA network because of buffering (which then requires me to close it and reopen it because it will not connect again unless I do). But then I'd have no problem watching Fox Sports on it during the same time but on a Saturday.
Like to point out that if your comcast doesn't give you the fox sports channel, you can get always get it off their app. Go figure huh? I know this because my buddy who's Xfinity it is, doesn't get Fox Sports where he's at, so he was surprised I was able to get it, and happy because he can watch it now.
Still have to use a mouse to get around with the app. Still have to sideload it from google play.
Oh, and it still doesn't stream the cartoon network/adult swim or the Comedy Central. Which is honestly making me look at the Sling option Dish is going to be doing in a couple months.
And that person with the error about device. That is weird. Uninstall it and then reinstall it to see if that fixes it.
For the remote I am thinking to buy a Mele F10 airmouse that I found is compatible with AFTV
