Echo Show 15 and Bell Fibe TV voice commands

Does the Bell Fibe TV app on the Echo Show 15 allow voice commands for channel switching? I signed into my Bell Fibe account and tried to use it on the Echo Show 15....I could launch the app via voice.  But I could only tune to one channel.  Meaning I could get it to open CNN (I think I asked for the channel number 1500) but after that, any other channel I asked for it to open .... it would say it was doing it, and it looked like it was doing it, but it only showed the channel I was previously watching, CNN.  I could change channels manually using the Fire remote, but not by my voice.

Same performance after I rebooted the Echo Show 15.

I called Amazon and they said VOICE COMMANDS ARE NOT SUPPORTED ON THE BELL FIBE APP ON THE ECHO SHOW 15.

(But then Alexa+ said voice commands to change channels IS supported)

I returned the Echo Show, 

But I am curious
