Currently we have Teams defaulted to show you the first (up to five) channels ever created. If you want to add more channels to your left rail view, just click the ellipses next to the channel name and select “Favorite”. When you favorite the channel, it will then be “pinned” to your left rail under that team name.
Try that and let me know if that meets your needs!

I'm having the exact same problem as Heather Herttna, comment from Heather copied below:
"I am unable to favorite a channel I just created (there is no option in the more options to do so) and I also cannot get the channel to 'show'. When I click on the more options, and then click on 'show' I just get an error message saying 'Couldn't show [channel name]. Try again.' (Trying again does nothing). I also created the channel to be always shown, but that obviously didn't work either. Something needs to be fixed here."
I've also attached a screenshot of the errors. I can "show for members" but it won't let me click the "show for me" without an error.
