I have BlueSky TV for about a month and live buffer is not working for at least two channels.
Toggling between two or more channels to skip commercials is a great feature.
On old Shaw Gateway I could toggle between last 6 channels, with buffer.
I believe that Shaw did this on purpose so it makes it more difficult to skip commercials.
If this feature will not be added, maybe I should switch to live streaming (internet) or Telus.
