unable to watch any of the cbc channels on telus tv plus?

I don't believe the TELUS TV+ app is able to accurately determine what connection you're using on third party devices.  They've done something to bypass the issue in the case of CBC because CBC somehow blocked streaming on-the-go from the channel's side for some reason, around the time the Olympics started.  You may yet need to power cycle your modem to gather a new IP, and clear the app-data and cache and force stop the app on some third party devices before logging back in.  (I'm using a Sony TV so we had a chuckle that the app seemed to think I was carrying it around with me away from home!)  On other devices, you may only be able to un/re-install the app to accomplish that.  Your mileage may vary as TELUS did a LOT of work with me over the phone on the provider side to fix other issues with my profile/account before anything finally worked...but clearing the full cache and signing back in today is what finally worked for me.  (Oh, side note: CBC News Network is now considered a 'premium' channel, not included for free with basic CBC as before - so you may need to add it 'officially' to your package now.  I would recommend using an agent to do so to get the best deal and ensure the profile syncs properly, especially if you are making other changes.  I have no idea if this change or distinction had anything to do with the issue of-mention.)
