On demand browse by network is gone

Ok Xfinity 

since you skipped beta testing of the new app and chose to test it by directly fielding it, here’s our list of what is gone that needs to be fixed for a Samsung smart TV

1. Favorite channel guide view

2. on demand search by network without having to type letters 

3. Last watched functionality. I like to tune 3-4 channels showing college football games and cycle between last watch to change games

4. Filter for Hd only

5. Fix guide view so I don’t have to go all the way back to channel 2 to activate the options at the top of the screen

I’ll add more as we find them.  But this interface is miserable.  Give me the option to go back to the old App
