Xfinity Stream App Beta TVgo availability

I've been going through the forums and I've come to learn that it may be a programing limitation as to why the regular channels for NickJr and DisneyJr are only available as SD programming instead of HD. However, I find that on the Stream App on my phone and tablet I can go to the TVgo channels and get the same programming in HD.

If we cannot make the regular channels be HD (maybe you can, if there's something I can do to get that let me know); can the app be updated to allow viewing TVgo channels through the Stream App on Roku?

I know it's still technically a beta, so maybe this is something that can just be a software update to the Roku App? I'd appreciate if someone can look into it, or simply get my feedback to those who can use and apply it? 

Thanks
