Apple TV Browsing Experience - Questions or Requests

Hi all,

Really new to the DirecTV Stream and I'm using it on our Apple TV.  The quality is good and the responsiveness is great.

I have some useability issues though and wanted to ask the group here:

1) Whenever I go to the search feature in the directv guide, if I "enter" text by using Siri to type it out for me, it won't let me select anything.  If I type it out manually by selecting the letters then it works just fine.  Is this just a me thing?

2) Is it possible to enter channel numbers or, even better, just say into siri what channel I want to jump to?  If it's not possible (and won't be possible) to do the voice jump (e.g. "ESPN") would it be possible to get a shortcut in the guide somewhere that lets me type in channel numbers?  Obv the apple remote doesn't have any numbers so i'd need a way to "type" them in.

3) Is there any way to make it harder to accidentally exit the app?  I find I'm jumping out of the app a lot on accident trying to get between guide and video or other selections.

4) Finally the apple remote on the phone has a channel up/down button but nothing happens on directv app when I push these.  Is that expected?

Sorry for blasting these out just a few quick observations with 24hrs of experience or so.

Cheers.

Dedric
