I followed the link to apple app store and the link only takes me to a preview. I tried searching for the app at the store no netflix app appeared. I have a MacBook air and any app only says iPhone or iPad. I am no further ahead and I still can not download any app for netflix so I can download movies to take on the plane.
In your case, could you please update the firmware of your Capsule II to the latest V9.5.16 through settings>device preferences>about>system update and see if you could control Netflix well via mouse mode on Nebula Connect app?
Continually press up and down on the nebula remote to keep the interface from disappearing. (Pressing left or right will skip forward or back and remove the interface. Idling for a few seconds will remove the interface as well and force me to repeat from step 1 again)
On the nebula connect app, use mouse mode to move the mouse to desired function, for example, subtitles. (All the while pressing up and down on the nebula remote to keep the interface from disappearing)
So I can now access all functionality, however it requires the use of two devices and complex movements to reach desired outcome. This is a very positive step in the right direction, but I am still working with customer support on how to get this the rest of the way to full functionality. If left and right prompted left and right, rather than skip forward or backward, it seems it would be perfect!
What I did was download a mouse toggle for android tv:
use Downloader, search on MATVT ( )
Set boss key to 4 (long press back button remote to enable mouse mode)
Under apps, special app access, display over other apps, allow MATVT
Under device preferences, accessibility, enable mouse toggle service.
