Hi @christothes , re your comment that led to this issue being created

I'm sure that I'm missing information, but why does the az CLI work fine with this tenant scenario, if as per your comment there is something fundamental that needs to be addressed for VS/VSCode token providers to work. I'm just curious why they can't do the same thing that allows the CLI to work fine in this case.

Our org has been running into this too and it has been a real pain for us.
In this related issue, Anais said that they created an internal request for VS to address this.
