This feature request has moved to the planning stage. There have also been several small updates that have gone out already, as well.
I’ll keep you posted as I hear more about coming updates.
We are actively looking into getting this fixed. Stay tuned for further updates!

I'm in the same boat. I have a free tier VSTS that will move to a paid version when my small indie team get's bigger and can afford it. I was hoping to use the free tier Teams as well considering they are suppose to work together yet Slacks free tier works just fine.
